The interaction between the supersonic jet and an obstacle is one of the fundamental problems of the compressible fluid dynamics, and causes the various problems of the aeronautical and other engineering, such as the design of a rocket launcher system. It seems that the characteristic of the interaction between the rectangular jet and an obstacle is necessary to control the interacting jet, but it is not conducted in past papers for the characteristic of a rectangular jet. This paper aims to clarify the characteristics of the interaction between the rectangular jet and an obstacle by the experiment and the numerical analysis.
