摘要 基于三维不可压流体的雷诺时均方程和Spalart-Allmaras方程湍流模型,采用SIMPLEC算法,对大型竖井贯流式泵站的全流道进行数值模拟,分析流道的流态和叶轮的静压分布规律,揭示竖井式贯流泵流道流体的流动机理;对泵装置的流量和效率进行预测,并与模型试验结果比较分析.结果表明:出水流道内的流动为轴向流动与环向旋转的螺旋形合运动;叶片的静压分布呈现较为明显的规律,升力面的静压整体上较吸力面要高,且叶片吸力面的静压等值线分布较升力面密.性能预测结果和模型试验结果吻合较好.

Abstract: Based on the Reynolds-avaraged equations of three-dimensional incompressible fluid and the Spalart-Allmaras one-equation turbulence model,the whole flow of Shaft-Well Tubular Pumping Station was numerically simulated by using SIMPLEC algorithm.The flow pattern in flow channel and the static pressure distribution on the impeller were analyzed to reveal the flow mechanism in the Shaft-Well Tubular Pumping channel.The flow rate and efficiency of the pump device were predicted and compared with the model test results.It is shown that the flow in the out flow channel is a spiral movement combining axial and rotary moving,and blade static pressure distribution takes on a obvious rule with higher static pressure on the lifting surface than on the suction side and denser contour distribution on the suction surface than on the lifting surface.Performance prediction results coincide well with the model test data.
