| Abstract: | The CFD simulation has been accomplished for the NASA low-speed centrifugal compressor in whole flow-rate range by selecting different numerical models and numbers of grids. The comparison between numerical and experimental results shows that the computation is comparatively accurate. And a proper numerical method is ascertained for CFD simulation of low-speed centrifugal compressor with vaneless diffuser. At the same time, some characters of the flow field in the impeller are analyzed under the condition of small flow rate near stall. |
