Abstract:

Numerical simulation of internal flow within double-suction pump is carried out based on the Reynolds Average Navier-Stokes equation and k-ε model with a simple algorithm. According to the simulation results, the internal flow and the calculated performance of doublesuction pumps are analyzed. The calculated results of performance prediction of the pump are compared with experimental results, showing good agreement under large flow conditions. The flow field simulation provides a useful basis to optimize design of double-suction pumps.
