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。
Using the upwind TVD scheme, the numerical simulation of the flow field around a non-side jet and a head-side jet with supersonic velocity was carried out. The results show that the side jet can reduce the frictional resistance of the shell surface. Cheng technology has some reference value.
