The flow around a rotating circular cylinder placed at various hights above a moving plate has been investigated numerically and experimentally for the high Reynolds number(Re=3.3×104∼6.6×104). The flow was affected considerably by the boundary layer on the moveing plate and the initial conditions of the experiment. Starting from different initial conditions, two different flow patterns were observed for smaal gaps(0.03&inE;H/D&inE;0.12)under the same experimental conditions. The transition of the flow pattern occeurs when the jet through the gap swiches from the moving plate to the cylinder wall. This phenomenon is known as some kind of the Coanda effect. Computation of the two-dimensional unsteady Navier-Stokes equations was also conducted. The numerical results qualitatively agreed with the expermental ones. The standing vortex was found at 2.5 diameters behind the cylinder in the case of Coanda effect.
