摘要 本文提出了超音速绕零攻角圆锥体的数值解法。通过解微分方程组而获得激波与锥体表面间的锥型流场,因而此方法不同于现有的近似解法或精确的图解法。编制了完整的计算机程序。实际运算证明,此解法不仅叠代过程收敛快,占机时少,而且使用方便。与已有的精确解比较,结果完全相符。 A numerical solution of supersonic flow past a cone without angle of attack is presented. By solving a set of differential equations the conical flow field between the shock wave and the conical surface is obtained, so this method differs from either any approximate solutions or the accurate graphic method.A computer program has been provided. It is proved by actual calculations that the present method has the advantage of fast convergence in iteration, needing less computer time, and convenient in operation. The Comparison of the results with other accurate sources has shown good coinence.
