The numerical investigation of the self-induced flow oscillation caused by the interaction of a supersonic impinging jet is carried out in this paper. The self-induced flow oscillation occurs at the specific conditions and causes the noise problem. The characteristic of the oscillated flow and the mechanism of the oscillation, therefore, have to be cleared to control the oscillation. This paper aims to clear the characteristic of a pressure fluctuation during the under-expanded supersonic jet impinges on the perpendicular plate. The TVD numerical method is used in the numerical analysis. From the results of numerical analysis, it is concluded that the pressure fluctuation on the plate surface depends on the pressure ratio and the position of a plate.
