Abstract In order to improve the performance of submersible axial pump and to attain the rule of inside flow field,the standard κ-ε turbulence model and SIMPLEC algorithm are applied to simulate the full flow passage of the ZQ2870C-4 submersible axial pump by CFD.According to the rule of distribution of velocity and pressure on surfaces of blade and guide blade,the design deficiencies of the pump at axial section flow channel and blade are pointed out,and the optimum profiles of blade,guide blade and the shape of axial section flow channel are obtained.Based on the simulation,performance curve of the pump is predicted.The result of the computation indicates that the value of prediction accords with experimental data at design condition.Further study is required for the turbulent model at the off-design condition.
