Abstract

In order to study the influence of lip clearance flow on the performance of a transonic compressors high-load transonic fan's rotor with five constant width clearances and two step-clearances were numerically simulated. After analysis of the overall performance parameters and the detailed flow parameters including the static pressure, circumferential velocity and entropy, it is concluded that the front part clearance flow has greater influence on the compressor than the back part clearance flow. In particular, the vortex-shock interference may worsen the front part clearance flow, as demonstrated by comparing the simulation of two step-clearances.
