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。 Based on the two-dimensional shock kinetic equations of the moving airflow, a new method to calculate the in-plane disturbance of the shock wave and the cone-head shock wave is proposed in this paper. This method can calculate the intensity and shape of the penetrating shock wave, the trajectory of the three-wave point during the Mach reflection, the strength and geometry of the Mach rod, and the magnitude of the peak pressure of the cone. The results are compared with numerical simulation, other calculation methods and experimental data. The results show that this method not only has higher accuracy, but also has the advantages of simplicity and saving time.
