Summary:The relative flow patterns of a centrifugal blower impeller were visualized on the planes of hub, intermediate and shroud by the spark tracing method simultaneously visualizing stream lines, that indicates the flow direction. The stationary image of flow patterns in the impeller was observed using the rotating image stopping processor in which a triangular prism rotates at the half angular velocity of the impeller, and quasi three-dimensional relative flow velocity distribution were obtained. Experiments were carried out in the region of small, design and large flow rates and the flow patterns of each region became clear. The surging phenomena were observed clearly at the small flow rate.
