分区算法数值模拟弹丸绕流流场

NUMERICAL SIMULATION OF EXTERNAL FLOWFIELD OVER PROJECTILES USING ZONAL APPROACH

利用分区计算技术 ,从 Euler方程出发 ,应用三维隐式有限体积 TVD格式 ,数值模拟了高跨音速下 SOCBT弹丸和超音速下尾裙弹的绕流场 。

Based on zonal approach, two kinds of external flowfields of SOCBT projectile at transonic speed and flared projectile at supersonic speed are numerically simulated. The three dimensional Euler equations and implicit finite volume TVD scheme are applied. The comparison between the calculation results and the experimental data shows that the method is feasible.
