| Abstract: | Parts of the MUSCL scheme are modified to simulate the forming process of flow field structure numerically for a supersonic jet exhausting out a jet nozzle. Tendency of variation for various system of waves in the flow field and the time at which the flow field comes to a steady state are given by results of numerical simulations. The results show that the present scheme has advantages including high resolution to shock wave, low oscillation and high efficiency in numerical calculation. At the same time, some valuable conclusion for the jet nozzle design have been obtained. |
