Computational analysis on static internal flow field of shock vector controlled vectoring exhaust nozzles

After comparing the results of three different turbulence models in computing static internal flow field of shock vector controlled vectoring exhaust nozzles by means of second order upwind schemes,(RNG) k-turbulence model shows to be the most valid turbulence model,and the computation results have been compared with that of the scaled model experiments.The results indicate that small nozzle pressure ratio and large inject mass flow rate will result in a larger vector angle.
