Abstract：Based on Reynolds Time-Averaged N-S equations and the standard k-ε turbulent model,FLUENT software and SIMPLEC algorithm were used to simulate the three-dimensional incompressible turbulent flow fields in an axial-flow pump with and without front guide impeller under the design condition.The velocity and pressure distributions were obtained and analyzed.Meanwhile,performance predictions,and analysis of the head and efficiency with or without front guide impeller were done under different flow rate.With front guide impeller performance instability region became narrower,and its efficiency slightly decreased.By analyzing the interior flow field characteristics and the influence of front guide impeller on the performance of the axial-flow pump,beneficial references can be provided to its hydraulic optimized design.
