摘要：In order to study the effects of different turbulence models on simulation accuracy of the miniature super-low specific speed centrifugal pump,the RNG k-ε turbulence model and SST k-ω turbulence model had been used in numerical simulation by Fluent.The performance curves and the internal flow filed distribution of those two turbulence models had been analysed and compared with the experiment results.The results show that at the low flow rate conditions,the simulation accuracy of the SST k-ω model is lower than that of the RNG k-ε model,while at the high flow rate conditions,the result is just the opposite.In the whole operating conditions,the average simulation error of the SST k-ω model is 3.5%and that of the RNG k-ε model is 4.3%.
