中文摘要	The blade tip region clearance flow is important in centrifugal compressors, especially for the high charging ratio, transonic centrifugal compressors used in vehicles. The effects of the blade tip region flow on the performance of a high charging ratio transonic centrifugal compressor were analyzed using three-dimensional CFD analyses that showed the shock waves at the design, near surge, and choke points. At the design and near surge points, the leakage vortex from the full blade leading edge collides with the neighboring full blade pressure surface and splits into two parts while at the choke point, a full blade leakage vortex appears on the pressure surface. At different operating points, splitter blade vortices and full blade vortices flow out in the same blade passage, with the separated vortex and passage vortex dimensions and distribution characteristics being similar and with high losses in the corner region between the blade suction surface and the shroud.
