Abstract :
The measurement of the flowfield in vaneless and vaned diffuser of high speed centrifugal compressor is reported in this paper. The flow measurement was carried out using a laser two focus velocimeter. The blade to blade distributions of absolute velocity and angle are compared with numerical distributions. The numerical results were obtained by using three-dimensional Navier-Stokes solver. The calculations are conducted on isolated impeller in steady approach
