The blade shape design is one of the most important factor for improvement of efficiency or noise reduction of a centrifugal fan. However, it is not easy to analyze flow through impeller blades both theoretically and experimentally. This paper describes the experimental technique for velocity measurements in the centrifugal fans by means of image processing of double-exposure particle-imaging patterns obtained by using dual-beam-sweep illumination technique. In order to develop fundamental technique, the measured velocity field of flows through the impeller blades of the basic model of the centrifugal fan are compared with the results obtained by 3D numerical analysis. And then the method is applied to measurements of flow through the multi-blade fan. The results obtained give useful data to consider the characteristics of the fan.
