Flows developing around a rotating disk in a cylindrical enclosure were investigated by a three-dimensional numerical Flows developing around a rotating disk in a cylindrical enclosure were investigated by a three-dimensional numerical method and experimental observations. The thickness of the disk, the height of the enclosure and the radii of the disk and the inner wall of the enclosure are finite, and the gap width between the disk rim and the enclosure is not negligible. In the gap, a vortical flow is induced by the centrifugal effect. When the gap width is small, the basic flow, spiral rolls and turbulent spirals apper as the increase in, the Reynolds number, as can be seen in the case,where the gap width is almost zero. In the system with larger gap width, the flow changes directly from the basic flow to the turbulent spirals, and no flow with spiral rolls apperes. The flow patterns predicted by the numerical, method accord with those found found by the experiment observations.
