Experimental investigations on the effect of boundary layer suction for a circular cylinder with a two-dimensional slit placed along a diameter have been carried out. Flow characteristics around the cylinder for cases of intermittent boundary layer suction (Pattern I), alternate boundary layer suction and blowing (Pattern II) and transition regions were clarified. Particularly, the mechanism of the boundary layer suction, fluid flows in the slit and rear surface of the cylinder and the mechanism of the vortex formation in the wake were clarified.
