Abstract：This paper proposed a methodto modify the structure of mixing-flow pump so as to resolve the problem of formation of vortex near the headof its manifold and partial desorption from the outlet of its manifold in attempts to improve flow-distribution uniformity and reduce hydraulic head loss.The three-dimensional structure of the manifold was first discretized into grid network using IECM,and the turbulent water flow through it was then simulated using CFD model;the simulated results were used to help improve manifold structure.The results showed that a smooth transition between the connection pipe and the angle of branch pipe influences the distribution of water flow field,and modifying their designs could improve the flow field in the outlet of the manifold and reduce hydraulic head loss.
