摘　　要：采用ＴＶＤ 有限体积格式，数值模拟了超音速条件下不同飞行Ｍ 数时含侧喷流炮弹绕流场，通过对六种情况的计算和对比，表明不同飞行 Ｍ 数对含侧喷流炮弹绕流场和全弹气动特性有较大影响。A TVD finite volume scheme is applied to simulate the behavior of jets over artillery projectile with jet interaction. Six conditions with different flying Mach numbers in supersonic have been calculated,which shows that the flying Mach numbers have significant influence on the flow field and the aerodynamic characteristic of artillery projectile. The results are referable to decide working time of the jet interaction for more increasse of the range. [
