Abstract: Flow characteristics around/behind a porous circular cylinder and porous sphere in a wind tunnel are studied. The parameters are incoming flow velocity (Uin), air ejection velocity (Vw) from the surface of cylinder/sphere, and dimension/shape of cylinder/sphere. This study is divided into dual parts. First part deals with flow field with no air ejection from the surface of cylinder/sphere, and the second one deals with the flow field for air ejection from cylinder/sphere surface. Finally, for each cylinder/sphere, Vw and critical Uin that causes the wake returns to the rear of cylinder/sphere are correlated into equations, respectively.
