Increased knowledge of flow conditions within centrifugal compressors may lead up to an improvement of the compressor performance.For the purpose of the design of centrifugal compressors with higher aerodynamic. efficiency and better over-all performance, the author has carried out experimental investigation of three dimensional velocity distribution within centrifugal impeller for a given set of operating conditions, Which are a tip speed 37.3 m/s, and flow rates 0.026,0.022 and 0.013.Further, experimental velocity distributions have been compared with velocity distributions by the two dimensiona1 potential theory.The principal conclusions are as follows ; it is found that there is essentially a difference between experimental and theoritical velocity distributions in meridional plane, and the flow through passages separates into two parts, so that negative and positive pressure blade surface side.
