| Abstract: | In this paper, flowfield of a nozzle is simulated by MacCormack difference scheme. The computation is based on the Navier Stockes equations. By analyzing the pattern of the flowfield, it is found that the computational results are well agreement with the experimental results. Then the impingement of rocket jet on flat plate with a hole is numerically studied. The parameter distributions of the impingement of rocket jet are given. |
