Title: Application of Steady Multi-phase Position and Unsteady Computational Methods to the Numerical Simulation of Double Suction Centrifugal Pump
Abstract: In order to compare the steady multi-phase and unsteady calculation in double-suction centrifugal pump application,this article simulated the internal turbulent flow of the 150S-50 double suction centrifugal pump.Numerical simulation adopted realizable turbulence model and simulating calculated with two methods of steady multi-phase and unsteady in 7 cases.Based on the numerical simulation to calculate the head,shaft power and efficiency,the results show that: the results of unsteady simulation are closer with the experimental data.[Ch,4 fig.3 tab.10 ref.]
