Flow characteristics of the radial inflow are investigated in a closed rotating cylinder. This cylinder consists of the outer rotating casing and the inner fixed body providing the flow inlet and outlet. The cylinder can rotate at the speed in range between 0 and 6000 rpm. The fixed body can have the stirrer blade on its top. This time, both type with and without the stirrer blade were investigated. Using a transparent acrylic for the upper part of the casing, fluid flows with tracer particles were shot with a high-speed camera (HSC). Then, the visualized flow images were measured by Particle Tracking Velocimetry (PTV) analysis. The analyzed results are helpful in investigating the heat transfer characteristics of a certain type of rotating cylinder cooling.
