An impingement of two-dimensional axisymmetric supersonic jet on a plate is simulated numerically to evaluate the jet flow configuration on the plate with a real gas assumption. An explicit TVD-Upwind scheme is used for the Euler equations to evaluate interaction between shock waves. An experimental study of the underexpanded axisymmetric supersonic N2 jets impinging on a plate is also discussed. Pressure measurements on the plate surface and Schlieren photometries are performed to investigate the impinging jets. Numerical results with the Euler equations have a good agreement with the experimental results at the shock structure and pressure distribution on the plate. The results show that three types for complicated shock-shock interactions are revealed and that a stagnation bubble is formed due to triple point near the plate.
