摘要 建立了求解二维 Euler方程和 Navier-Stokes方程的 TVD有限体积格式 ,对口径为 38mm冲压加速器内弹丸周围的无粘流场和层流流场进行数值研究 ,模拟了冲压加速器内复杂的激波系 ,分析了冲压加速器内激波加热点火机理和弹丸速度的影响 . The TVD finite-volume scheme has be en developed to solve Euler equations and Navier-Stokes equation. It is used to simulate the flow field of ram accelerator with or without viscosity, the comp lex shock system is obtained. The principles of shock ignition and the influencl e of projectie velocity on flow field are also analyzed.
