摘要
本文利用高精度的TVD有限体积差分格式,对欠膨胀火箭多股自由喷流的干扰流场进行了数值研究,给出了两股自由射流的干扰流场的复杂激波系结构,包括内、外层反射激波、相交激波等波系结构。数值结果与实验结果较为吻合。
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.
