| Abstract: | The flowfield formed by the interaction of multi-freejets of underexpanded rocket has been numerically simulated by high resolution TVD finite volume difference scheme. The complicated shock structure of the interaction flowfield has been showed in this paper, which including the inner and outer lateral shock, the inner and outer reflected shock, slip surface and jet boundary, and so on.The numerical results show good agreement with those of the experiment. |
