• An investigation was carried out on various characteristics of a circular cylinder with tangential injection of air immersed in a uniform flow. As a result, it was found that a separation bubble took place where the radius of curvature of the cylinder was discontinuously increased even if the wall itself was smoothly connected; that the velocity profile of mixing region of jet was similar and cosine-like up to downstream of separation-point; that, when the intensity of jet was weak, the lift (drag) coefficient was reduced (increased) by injection of air when the station of the slot was up-stream of the laminar separation-point and that, when the station of the slot was downstream of the laminar separation-point, the control to fix the separation-point anywhere between the laminar separation-point and the station of the slot was impossible.
