摘要
Based on the standard k-ε turbulence model and the RANS equations, thefinite volume method and the SIMPLE algorithm were adopted to carry out the three-dimensionalviscous numerical simulation of the internal flow within a vortex pump in double reference frames.According to the results of numerical simulation, the internal flow in the vortex pump was analyzed,and the calculated results of blade surface pressure of the impeller were compared withexperimental results. The maximum relative error is 6.6% between calculated value and experimentalvalue of the pump head under operation conditions.
