| 摘 要： | 本文从运动气流的二维激波动力学方程组出发,提出了一种计算平面运动激波和尖锥头激波迎面干扰问题的新方法。该方法可以计算穿透激波的强度和形状,马赫反射时三波点的轨迹,马赫杆的强度和几何形状,以及锥面峰值压力的大小。计算结果与数值模拟、其它计算方法以及实验数据进行了比较,结果表明本方法不仅精度较高,而且保持了简捷,省机时的优点。

| Abstract: | On the basis of the two-dimensional shock dynamics equations in a flow gas, a new method of calculation about the head-on interaction of a moving shock with a sharp cone was presented in this paper. This method can be used to calculate the strength and shape of the transmitted shock, the triple-point trajectory of Mach reflection, the strength and shape of the Mach stem and the peak pressure on the cone surface. The results of calculation of this method was compared with that of the numerical simulation, that of other methods and the experimental data. The comparison shows that this new method not only has better accuracy, but also keeps up the merit of simplicity. |
