本文根据质量守恒原理,建立了二维超音速底部流动的解析模型。在忽略拐角处附面层厚度的前提下,计算了底部压力值。和实验结果比较表明,解析模型提供的压力值令人满意,同时还应说明,这个解析模型不难推广到有气体喷射的情况。 Based on the principle of mass conservation, this paper established a two-dimensional supersonic flow model. Ignoring the thickness of the corner at the corner, the bottom pressure was calculated. The comparison with the experimental results shows that the analytical model provides a satisfactory pressure value, and at the same time, it should be noted that this analytical model is not difficult to generalize to the case of gas injection.
