Influence of volute distortion on the performance of turbocharger centrifugal compressor with vane diffuser被引量：5
《Science China(Technological Sciences)》2013年第11期2778-2786,共9页ZHENG XinQian JIN Lei TAMAKI Hideaki 
supported by the National Natural Science Foundation of China(Grant No.51176087)
As the geometry of the volute of turbocharger compressor is non-axisymmetric,it causes a distortion at the outlet of the diffuser and influences the upstream components.A distortion model in which a pressure distortio...
