When the underexpanded supersonic jet impinges on the obstacle, it is well known that the self-induced flow oscillation occurs at the specific condition, namely the pressure ratio in the flow field, the position of an obstacle and so on. This oscillation is related with the noise problems of aeronautical and other industrial engineering so that the characteristic and the mechanism of self-induced flow oscillation have to be cleared to control the various noise problems. But, it seems that the characteristics of the oscillated flow field and the mechanism of oscillation have to be more cleared to control the oscillation. This paper aims to clear the characteristic of oscillation frequency, pressure fluctuation on the surface of cylindrical body and the control of self-induced flow oscillation during the impingement with the cylindrical body. The numerical and experimental investigations were carried out using the TVD method and discussed.
