摘要/Abstract

摘要： 利用迎风ＴＶＤ格式，在超音速下，分别对无侧喷流和头部含侧喷流的炮弹绕流场进行数值模拟，结果表明侧喷流能够降低炮弹表面的摩擦阻力，对研究炮弹的增程技术有一定的参考价值。

Abstract: The behavior of jets in super sonic flow field over a biconic body with jet interaction and no jet interaction were detailed numerical simulated using high resolvation TVD scheme.The jet inter action drag has been compared with no jet interactionThe computed results show that jet interaction decreased the surface drag of artillery projectilesIt is useful for the research of the range increasment of artillery projectiles
