计算强激波马赫反射的简易方法

A SIMPLE METHOD FOR THE CALCULATIONS OF MACH REFLECTIONS OF STRONG SHOCK WAYES

本文应防护工程实际需要,根据大量实验数据和数值计算成果,提出射线管截面积与激波马赫数之间的幂次函数形式,使得马赫反射区地面最大超压分布计算大大简化,且计算结果与实验值符合较好。本方法对高抗力防护工程设计计算有重要参考价值。

On the basis of a large amount of experimental data and results from numerical Calculation, an exponetial function for the relation between the ray tube cross-section and Shock wave mach number is presented in this paper. With Sucn a faction, the Calculation of the ground Surface Peak Overpressure distribution in the mach reflection region is greatly Simplfied, and the results of the Calculation agree fairly Well With experimental data. This method will be rery useful in the design of hardened protection Structuses.
