A numerical simulation using axi-symmetrical Navier-Stokes equation for gas flow inside an elliptical model was performed, in which supersonic jets emitted from inlet of the cell and the induced shock waves interfere with each other. The effects of the pulse width, initial Mach number, initial pressure ratio and initial temperature ratio of the jets emitted in the way of single pulse on the behavior of the jets and shock waves as well as their interference were investigated. As a result, it was found that an optimal condition for colliding of the jet and shock waves in the vicinity of focal point of the elliptical cell and so the jet flows out through the exit of the cell
