摘　　要：采用3阶的WENO格式计算了大气层内带有侧向喷流的超声速导弹绕流流场。计算显示了喷流和绕流干扰的流动结构。喷流上游的高压区域包络弹体,与喷流下游的低压区域一起削弱了喷流产生的侧向力。在文中计算条件下,喷流放大因子小于1,并形成了较小的俯仰力矩。A third order WENO scheme was used to calculate the flow field around the supersonic missile with lateral jet interaction. The calculation results show the flow field structure of jet interaction around missile. High pressure in the upstream spreads around the whole missile together with low pressure in the downstream weakens lateral force of jet. The flow field enlargement factor is lower than 1 under the given calculation condition and generate a smaller pitching moment.
