Abstract: When a shock wave propagates into a quiescent atmosphere of low pressure from a nozzle orifice, the flow can be simplied by solving a axisymmetric unsteady flow problem. In this paper second order accurate upwind schemes in total variation diminishing (TVD) type is employed for numerically simulating underexpanded supersonic free jet. A satisfactory time-dependent solution has been achieved.

Key words: gasdynamics, shock wave, jet flow, numerical simulation
