在对近年来有了很大发展的各种非等熵势函数方法进行理论分析的基础上,本文指出,从散度型动量方程直接求解密度并与势函数方程迭代的方法较为完善。这种方法既保持了势函数计算简便的优点,又扩大了势函数的适用范围,可以在跨声速计算中发挥很大的作用。
Based on the theoretical analysis of various non-isentropic potential functions that have been greatly developed in recent years, this paper points out that the method of directly solving the density from the divergence momentum equation and iterating with the potential function equation is perfect. This method not only retains the advantage of calculating the potential function but also expands the scope of application of the potential function, which can play a significant role in transonic calculation.
