为了达到提高初速和射程的目的，陆用远程火箭越来越多的采用复合推进剂作为发动机燃料，进而产生高温、高压、多组份含有限速率非平衡化学反应燃气射流，在发射时对武器装备产生强烈的冲击．本文构造了适合此种情况的有限体积ＴＶＤ数值格式，对某火箭武器的射流流场进行了数值模拟，并与试验结果进行了对比，证明此格式的应用是成功的．
In order to achieve the purpose of increasing muzzle velocity and range, more and more long-range rocket vehicles use composite propellants as engine fuel, thereby generating high-temperature and high-pressure multi-component jet streams containing rate-limited unbalanced chemical reactions. Equipment has a strong impact. In this paper, a finite volume TVD numerical scheme suitable for this situation is constructed. The jet flow field of a rocket weapon is numerically simulated and compared with the experimental results. It is proved that the application of this scheme is successful.
