One power plant's pump-turbine was modeled in order to analyze the field characteristic with low flow conditions in pump mode of pump-turbine.The flow characteristic in pump mode was simulated by SIMPLEC algorithm and shear stress transmission(SST) k-ω mode.The flow of runner and vanes was analyzed when pump mode was at the condition of that guide vanes were in designed opening and low flow.The performance of pump-turbine was analyzed combined with experimental results.Results show that the head line is in ...
