As previously explained，all experimental and numerical work is conducted on the single-stage，high speed，low flow rate centrifugal compressor.The design specifications of the impeller and diffuser are summarized in Table 1.The past numerical simulations indicate that there is a vortex in the diffuser passage of the compressor with smooth wall casing near stall condition[23].The overall performance obtained through the experiments and the flow passage data were referred for the validation of numerical simulations，which will be presented as follows.
