109 Research progress on solid-liquid two-phase flow characteristics and erosion of centrifugal pump
LI Wei,PAN Yunxin*,LI Haoming,QI Handong,WU Pu,LU Dele
Due to the wide application of centrifugal pump, the solid-liquid two-phase flow has become a common problem in the study of flow characteristics in centrifugal pump. The addition of solid medium leads to the decline of head and efficiency, and even causes serious wear on the inner surface of the pump, which has a great impact on the operation performance of the centrifugal pump and reduces the continuous operation life of the centrifugal pump. In view of the above problems, the research status of solid-liquid two-phase flow in centrifugal pump from the aspects of solid-liquid two-phase flow characteristics and wear were introduced, and the main research methods and research results were summarized, including particle size, density, volume fraction and operating conditions of the centrifugal pump, which provides a certain reference and research basis for further optimizing hydraulic and structural design, improving the performance, reliability of solid-liquid two-phase flow in centrifugal pump, and wear condition.

118 Hydraulic performance analysis of rear impeller of counter-rotating axial flow pump
XU Tian,CAI Yiping,CHU Shiji,SHI Lijian*,ZHU Jun,JIANG Yuhang
In order to study the impact of the rear impeller on the hydraulic performance of the counter-rotating axial flow pump, CFD software was used to carry out numerical model calculation of the coun-ter-rotating axial flow pump device. Initially, the hydraulic performances of the front impeller and the rear impeller were compared and analyzed, and the influence of the inlet angle of the rear impeller on the hydraulic characteristics of the entire device was studied. Finally, the reliability of the data was verified through model tests. The results show that under the design conditions, the head of the coun-ter-rotating axial flow pump is 11.32 m, with an efficiency of 87.57%. Under low flow conditions, when the flow rate is about 300 L/s, it enters the saddle area in advance with a head of 14.06 m, and an efficiency of 79.48%. Under high flow rate conditions, when the flow rate is 440 L/s, a head of 2.24 m with an efficiency of 54.16% is recorded. The flow inlet angle of the rear impeller of the coun-ter-rotating pump is greater than that of the front impeller, which leads to the enhancement of the wor-king ability of the rear impeller blades and the increase of the head of the rear impeller. By changing the placement angle of the rear impeller, especially under small flow conditions, the saddle area of the rear impeller is also advanced, and the inlet liquid flow angle of the rear impeller is almost the same. The research results provide a reference for the design and optimization of the rear impeller of the counter-rotating axial flow pump.

124 Effect of rotational speed of spiral shell on liquid flow characteristics in cavity
LIU Zailun,GU Shengfu*,ZHAO Weiguo,LYU Peitao,ZENG Jilai
In order to study the influence of the rotational, speed of the spiral shell on the liquid flow characteristics in the cavity, the experimental roto-jet pump was used as the research object. On the basis of verifying the accuracy of the synchronous rotation experiment and simulation results of the impeller and the spiral shell, the RNG k-ε turbulence model was used for numerical calculation for five models with the same impeller speed and different spiral shell speeds to analyze the change of the fluid flow characteristics in the cavity and study the performance of the pump. The results show that as the rotational speed of the spiral shell increases, both the peripheral velocity and the rotation coefficient of the liquid increase, the peripheral velocity curve gradually forms concentric circles along the radial direction, and the liquid in the cavity rotates non-rigidly. The radial pressure gradient of the fluid in the cavity increases when the pressure is lower than 624 kPa, whereby a higher rotational, speed results in a lower pressure. When the pressure is higher than 624 kPa, a higher rotational speed results in a higher pressure. The vortices in the upstream region of the collector are distributed near the inlet, and the vortices in the wake region are concentrated at the end of the diffuser section, resulting in an overall increasing trend. As the speed of the spiral shell increases, the head of the pump increases, but the efficiency decreases. By changing the diameter of the inlet of the collecting pipe, it is found that the collecting pipe is not the main reason for the decrease in efficiency, but the increase of the friction loss of the disc causes the decrease. The loss increases with the increase of the rotational speed of the spiral shell in a 3rd power function, and the optimal inlet diameter that is used in this paper is 13 mm.

133 Internal flow characteristics of single-stage and multi-stage side channel pumps
WANG Jinye,ZHANG Fan*,ZHANG Jinfeng,CHEN Ke,HONG Qiuhong
To study the influence of the initial stage centrifugal impeller on the performance and internal flow characteristics of a radial vane multi-stage side channel pump with low specific speed, an unsteady three-dimensional numerical simulation was carried out using the SST-SAS turbulence model on a single-stage and multi-stage side channel pump under different working conditions. The results revealed that the head of the multi-stage side channel pump improves after adding the centrifugal impeller as the first stage. The inlet pressure of the side channel impeller increases by 20%, the mass flow between the impeller and the side channel is also increased by about 20%. However, the distribution of vortices in the impeller of the multi-stage side channel pump is basically the same as that of single-stage and the addition of the centrifugal impeller as the first stage has little effect on the internal flow characteristics of the single-stage pump. The findings of this research paper provides a reference and theoretical basis for subsequent cavitation research and structural optimization of multi-stage side channel pumps.

140 Experimental study on mechanical properties and microstructure of powdered coal gangue concrete
LI Wen,WANG Hailong*,ZHANG Jiahao,YANG Hong,FENG Shuai
In order to explore the influence of rubber powder content on the mechanical properties of coal gangue coarse aggregate concrete, 20 mesh rubber particle content(0, 3%, 6%, 9%, 12%)of rubber powder coal gangue concrete was designed, and the macroscopic mechanical test and the microscopic pore structure nuclear magnetic resonance test were carried out.The results show that the increase of powder content is negatively correlated with the mechanical strength, and the effect of 3% powder content is the least, which is 1.3% lower than that of the reference group. Fitting the conversion formula of cubic compressive strength and splitting tensile strength of 20 mesh gangue concrete with different powder content has a good correlation. The addition of rubber powder reduces the proportion of harmful pores, and the content of 6% rubber powder reduces the distribution of harmful pores in gangue concrete by 4%. The data show that the rubber powder particles can fill the pores, reduce the occurrence of damage pores and optimize the pore structure. A GM(1,3)model is established by selecting the most influential factors on the strength: bound fluid saturation(correlation degree 0.951 06)and pore radius ratio greater than 0.02 μm(correlation degree 0.963 86).The average error predicted by the model is 2.56%. It provides a reference basis for the green concrete which can be used locally for the slope protection material of mine dump.

147 Lag of channel return flow in Jingdian Irrigation District Phase I
GAO Qiuyan,ZHANG Jinghui,FEI Liangjun*,JIE Feilong,LI Shan,LI Jingsi
In order to reveal the lag law of channel return flow of the Yellow River Diversion Irrigation Area in the arid area, according to the monitoring data of the channel return flow of Jingdian Irrigation District, the cross-correlation coefficient method and data translation method were used to determine the lag time of return flow in the irrigation area, and the temporal and spatial variation law of return and its influencing factors were analyzed. The research shows that there is little difference in the annual return flow of each water outlet. The average annual return flow is about 46.223 million m3, accounting for 31% of the irrigation water diversion. There is a large difference in the amount of return flow from different water outlets, among which Xiangshui Village accounts for 67% of the total return flow, Wufo Township accounts for 30.6% of the total return flow, and the Total Pump I in Phase II accounts for 2% of the total return flow. The main influencing factors of the monthly return flow of different water outlets in Jingdian Irrigation District are the control area of the outlet and the lag time of return flow. The factors affecting the lag time include water diversion, precipitation, the length of the return flow path and manual excavation of drainage channels. The lag time of different outlets is between 1-5 months. The lag of Xiangshui Village is stronger than that of Wufo Township and the Total Pump I in Phase II. The lag of return flow caused by irrigation and water diversion is different. The lag effect of return flow and its influencing factors revealed in this study can provide theoretical support for rational allocation and precise regulation of water resources in Jingdian Irrigation District.

153 Study on the influence of oil level change on oil mist leakage problem of generator thrust bearing oil tank
XU Lijun,YANG Xiong,HONG Yunlai,NIE Sai,ZHANG Zhiping,SUN Jie,ZHANG Yuquan*,ZHENG Yuan
A three-dimensional thrust bearing model was established to solve the oil mist leakage problem of thrust bearing in Jiangxi Hongping Pumping and Storage power Station. The VOF multiphase flow model, Lee evaporative condensation model, and RNG k-ε turbulence model were used to solve the lubricating oil-air-oil mist three-phase fluid-thermal coupling problem in the oil tank. The influence of the change of oil level height from low alarm level to high alarm level on the distribution characteristics of the flow field in the oil groove was analyzed, and the distribution of lubricating oil and the accumulation of oil mist under different oil levels were explored. Also, the generation and accumulation positions of oil mist were located. It is found that the unit speed and the external circulation pump performance mainly determine the oil tank velocity and temperature distribution. The oil mist mainly gathers in two areas after it is generated. One is the area between the oil baffle and the thrust head, and the other is the area at the oil pipe. These two regions are characterized by low pressure, high temperature, and high velocity and are most prone to external and internal oil dumping. In addition, with the high-speed increase in oil level, the oil pressure cascade gradually loses its oil mist suppression effect. The thrust bearing oil groove is not recommended to operate at a higher oil level for operation safety and environmental safety. This paper can provide a theoretical basis for reasonably setting the operating parameters of a thrust oil tank.

WANG Yong,ZHANG Guoxiang*,LIU Houlin,XIAO Yadong,LI Gangxiang,LI Ming
Considering the hydrodynamic cavitation intensity and pumping liquid, based on a single-stage single-suction centrifugal pump with specific speed of 117.3, a new type of rotational hydrodynamic cavitation generator was designed. The CFX software was used to analyze the cavitation pattern and the law of cavities evolution of the rotational hydrodynamic cavitation generator. The results show that the cavitation groups of the rotational hydrodynamic cavitation generator can enlarge with decreasing inlet pressure and increasing flow rate. The cavities initiate around barricades and the tongue, the cavities in rotator initiate at the side of barricades and fall off behand the barricades close to tongue, the cavities near tongue fall off at the same time with the vapors behand barricades, however, they have different collapse periods. This novel rotational hydrodynamic cavitation generator improves the level of integration and has good cavitation effect and high head. The study of cavitation cha-racteristics can provide a reference for hydrodynamic cavitation generator design.

167 Effect of wind direction changing speed on power and speed of wind turbine
DU Yunchao,WANG Jianwen,*,WANG Yingzheng,ZHANG Jianwei,YAN Sijia
In order to explore the change of wind turbine output power when the wind direction changes, an S-airfoil three blade horizontal axis wind turbine was taken as the research object. The rotating platform was used to simulate the process of uniform change of wind direction. The upper limit is the speed of extreme wind direction angle change of 5 °/s specified in IEC-61400. One wind direction change speed was selected every 1°/s, that is, five wind direction changes were selected as wind speed, i.e. 1, 2, 3, 4 and 5 °/s, to study the variation of wind turbine output power and speed under different wind speeds. The results show that the output power and speed of the wind turbine show a fluctuating downward trend under different wind speeds. The results show that the output power and speed of the wind turbine fluctuate and decline under different wind speeds, the greater the wind direction speed changes at the same wind speed, the faster the decline rate, but the lower the corresponding decline amplitude in the process of wind direction change; there is a hysteresis phenomenon at the beginning and end of wind direction change, and the output power of the wind turbine has a small amplitude at the beginning of wind direction change after the wind direction changes, the output power and speed of the wind turbine need to continue to run for a period of time to reach a stable value. The greater the speed of wind direction changes, the longer the delay time, the greater the initial tip speed ratio, and the greater the final stable value.

173 Vortex characteristics of horizontal axis wind turbine blade and wake flow field based on dynamic mesh
GAO Wei,ZHANG Liru,*,YAO Huilong,YAN Rong
In order to study the generation and evolution process of vortices in the flow field of wind turbines, the overlapping grid method in the moving mesh technology was droped to calculate the flow field of horizontal axis wind turbines, and the Q criterion was used to carry out visual analysis on the structure of blade surface, tip vortex and central vortex, and the calculated results with those calculated by sliding mesh under the same working condition were compared. The results show that by comparing the vorticity distribution of blade surface with the two methods in different sections, the flow separation area on suction surface is larger and more details of boundary layer separation on blade surface can be captured by the moving mesh method. The ″tip vortex jump″ phenomenon occurs when the tip vortex moves downstream. In the wake flow field, the vortex distribution of the central vortex is bimodal. In the range of 0.5D~2.0D behind the wind turbine, the tip vortex and the central vortex have mixed diffusion. The distribution trend of the central vortices in the wake flow field is basically the same according to the calculation of the moving grid and the sliding grid. The vortex peak value is larger according to the moving grid method, and the central vortices are diffused earlier according to the sliding grid method. Compared with the sliding mesh method, the moving mesh method is more advantageous to study the vortices in the flow field of wind turbines.

YIN Yongle,FEI Liangjun*,LI Zhe,LIU Teng,LI Zhongjie,HAO Kun,PENG Youliang
In order to explore the effects of different irrigation and nitrogen application on growth cha-racteristics and yield of apple trees under surge-root irrigation in mountainous areas of northern Shaanxi, field experiments were carried out with different apple trees. Three irrigation levels were applied: 85%-100%(H1), 70%-85%(H2)and 55%-70%(H3)of the field water capacity, respectively, and three nitrogen levels were N1(360 g/plant), N2(240 g/plant)and N3(120 g/plant). The results show that irrigation and nitrogen application has significant effects on new shoot length, flowering, fruit-setting, fruit diameter, fruit volume and yield of apple. The leaf area index(LAI)shows a singlet trend during the growth period, and the peak value appears in the middle of July. Under the same irrigation level, compared with N3, N1 increases in yield, new shoot length, LAI, transverse diameter, longitudinal diameter, volume, flowering and fruit setting by 17.91%, 28.31%, 18.75%, 11.38%, 10.13%, 36.60%, 20.92% and 5.19%, respectively, while N2 also increases by 12.40%, 15.63%, 4.86%, 5.40%, 5.11%, 17.01%, 26.17% and 13.74%, respectively. The rate of flowering and fruit setting decreases with the increase of nitrogen application. Under the same nitrogen level, compared with H3, H1 increases in yield, new shoot length, LAI, transverse diameter, longitudinal diameter, volume, flowering and fruit setting by 34.65%, 15.49%, 30.77%, 3.93%, 4.95%, 12.86%, 33.15% and 28.62%, respectively, while H2 also increases by 33.67%, 16.42%, 67.52%, 3.81%, 2.97%, 11.57%, 43.45%, and 27.26%, respectively. The rate of flowering and fruit setting decreases first and then increases with the increase of irrigation amount. Compared with H3N3, the yield of other treatments increases by 2.69%-52.20%, While H2N1 treatment has the highest yield(26 852.55 kg/ha). Considering from the point of view of promoting growth and increasing yield, the best water and nitrogen combination mode of mountain apple in northern Shaanxi is medium water deficit irrigation and high nitrogen(H2N1)treatment. The results from this study can provide a theoretical basis for apple water and nitrogen management in mountainous areas of northern Shaanxi.

WANG Qian,TUO Yunfei,WANG Fei,SHEN Fangyuan,ZHENG Yang,DU Wenjuan,XIANG Ping,YANG Qiliang
To investigate the effect of micro-sprinkler irrigation fertilization on soil nitrogen transport and transformation of Panax notoginseng, three irrigation levels of 0.4 FC(W1), 0.6 FC(W2)and 0.8 FC(W3)and four fertilization levels of 3.20(F1), 4.80(F2), 6.20(F3)and 120.00 kg/ha(F4)were set up at the Panax notoginseng cultivation base in Dalishu Village, Luxi County from 2017 to 2020, with CK as control, for a total of 13 treatments. The study was conducted to investigate the effect of different irrigation fertilization conditions on the transport and transformation of total nitrogen, nitrate nitrogen and ammo-nium nitrogen in Panax notoginseng soils under micro sprinkler irrigation. The results show that the soil total nitrogen content increases and then decreases with time, the nitrate nitrogen content decreases and then increases with time, and the ammonium nitrogen content gradually decreases with time under different irrigation fertilization conditions. Total nitrogen and ammonium nitrogen content gradually decrease with increasing soil depth, while nitrate nitrogen content first decreases and then increases with increasing soil depth, with total nitrogen, nitrate nitrogen and ammonium nitrogen tending to accumulate in the soil layer 0-10 cm, with W2F3 soil having the highest total nitrogen content, W2F3 soil having the highest nitrate nitrogen content and W2F4 having the highest ammonium nitrogen content. The amount of irrigation water is highly significantly correlated with soil nitrate nitroge and soil ammonium nitrogen(P<0.01)and negatively correlated with soil total nitrogen(P<0.05), while the amount of fertilizer applied is positively correlated with soil nitrate nitrogen and highly significantly correlated with soil ammonium nitrogen(P<0.01)and significantly correlated with soil ammonium nitrogen(P<0.05). This study aims to clarify the characteristics of irrigation fertilization in regulating nitrogen transport and transformation of Panax notoginseng in acidic red loam soils, improve the micro-ecological environment of farmland, enhance water and nitrogen use efficiency, and provide technical support and theoretical basis for effective pest and disease control.

196 Effect of ecological cultivation pattern on water footprint of paddy field
LI Xuechun,CHEN Dan*,WANG Linlin,MA Yu,YE Zhihao,WU Songwei,LIANG Yifan
A water footprint accounting method for the rice-crayfish coculture field, located in Lianshui County of Huai′an City, Jiangsu Province was developed. An integrated view between the water consumption patterns and the blue, green and grey water footprints for the different cultivation patterns at different stages were provided. The results show that there are differences in the irrigation quota, unit production water footprint and the compositions of rice under different patterns. The irrigation quota for the rice-shrimp ecological cultivation is 24 922.95 m3/ha, which is 5.75 times for the traditional rice cultivation. The water footprint of rice production is 19.9 m3/kg for the former, much higher than 11.9 m3/kg for the latter. The green water footprint is the highest in the compositions of production water footprint for the traditional rice. For the rice-shrimp ecological cultivation, the gray water footprint is the highest, far higher than the green and blue water footprint. From the perspective of water footprint, the water use efficiency for the rice-shrimp ecological cultivation in the study areas can be improved though water-saving and emission reduction strategies.

203 Experimental study on the influence of ″Groove-type″ drive plate on the hydraulic performance of jet pulse sprinkler
YAN Hailan,WANG Xinkun*,YAO Jicheng,HUANG Jianxiang,ZHAO Wenhe,MENG Tianshu,WANG Xi
In order to improve the radial water volume distribution of the jet pulse sprinkler, based on the ″double hump″ type water volume distribution of the jet pulse sprinkler and the characteristics of the water baffle structure, innovative the ″groove-type″ drive plate structure, and the orthogonal test was carried out to obtain a new type of the jet pulse sprinkler. The results show that the primary and secondary order factors, which affect the optimal structure of jet pulse sprinkler irrigation on the uniformity,are that the inclination angle of the inner groove is 13°, the length of the driving plate is 16 mm, the groove width is 3 mm, the inclination angle of the side drive plate is 17°, and the width of the driving plate is 11 mm. When the inlet pressure is 0.15, 0.20, 0.25 and 0.30 MPa, the hydraulic performance comparison test of the ″groove-type″ the jet pulse sprinkler, original jet pulse sprinkler and rocker arm sprinkler was carried out. The test results show that under the inlet pressure of 0.15 MPa-0.30 MPa, the inlet flow rate of the new sprinkle is reduced by about 0.12 m3/h-0.17 m3/h compared with the inlet flow of the original sprinkler, and the inlet flow rate of the new sprinkler is about 0.07 m3/h-0.16 m3/h smaller than that of the rocker sprinkler. The uniformity of the sprinkler irrigation of the ″groove-type″ new sprinkler is 1.25%-7.43% higher than that of the original sprinkler, and 7.84%~14.42% higher than that of the rocker sprinkler. The comprehensive analysis shows that the structural design of the ″groove type″ drive plate is reasonable, and the uniformity of irrigation to the nozzle is significantly improved. This study can provide theoretical reference and data support for the subsequent research and development and engineering application of this type of domestic sprinkler.

210 Effects of casing length and emitter flow rate on infiltration characteristics of spring root irrigation
LIU Keyao,WU Pute,Symbolj@@,ZHU Delan,CAI Yaohui,SONG Xiaolin,WANG Jianping
In order to determine the suitable application parameters(flow rate and casing length)for root irrigation of apple springs in the Loess Plateau, PP cotton filter element was selected as the supporting casing for indoor soil box tests to explore the influence of the emitter flow rate and the casing length. The test results show that a large emitter flow rate is conducive to the migration of soil moisture in the vertical direction. The larger the flow rate, the greater the volume of the wet body, the range of high-water content areas in the wet body, and the maximum water content at the end of irrigation also increases accordingly after the redistribution of soil water. The accumulated water in the casing can increase the infiltration surface and the infiltration water potential gradient, thereby significantly increa-sing the migration rate of soil moisture. The interaction between the emitter flow rate and the casing length will directly affect the horizontal and vertical migration of soil moisture. When the emitter flow rate is 12 L/h and the casing length is 40 cm, the volume of wet body formed is the largest, and the water distribution in wet body is more uniform, which is the most conducive to the horizontal and vertical movement of soil moisture in the horizontal and vertical directions. This study will provide technical reference for the spring root irrigation technology in Loess Plateau.
