摘要
Abstract
The hub and shroud contours are redesigned for a high hub/tip ratio centrifugal compressor with the same axial dimension. Detailed analyses of the flow visualization have exposed flow topologies between the cases with original compressor and modified compressor by numerical simulation, therefore led to some preliminary conclusions as to the flow physics involved in the compressor performance improvements afforded by the redesign of hub and shroud contours.关键词
