摘      要：This paper performs a numerical simulation of three-dimensional flow field in a centrifugal compressor with long inlet and outlet pipes using CFX *** arranging virtual probes at different positions in both inlet and outlet planes,the aerodynamic performance of the centrifugal compressor is measured and compared with each *** effects of measuring positions on measurement results are *** results show that it will generate notable measuring errors of the pressure ratio and efficiency if the inlet total pressure is measured using a single-point *** inlet total pressure data can be accurate when they are measured using a 3-point *** outlet total pressure and total temperature data can not be accurate if they are respectively measured at one circumferential position even using a multi-point *** tangential measuring positions at the outlet is effective to improve the test *** the outlet total pressure and total temperature are respectively measured at 3 tangential positions,the data can be almost accurate.
