摘　　要：侧向喷流是导弹在中高空进行姿态控制的重要手段。本文用数值方法求解N-S方程,模拟了二种带侧向喷流控制的喷流与绕流的干扰流场。通过定性流场结构和物面压力分布与实验结果的比较,数值模拟能较好地模拟侧向喷流与外流干扰产生的复杂流场特性。给出了合理的流场结构和干扰气动力特性,表明数值方法可以作为型号侧向喷流控制设计的研究手段。Lateral jet is an important means for missile control in high altitude. In this paper, two kinds interaction flow fields with lateral control jet are studied numerically by solving N-S equations. Through comparison of flow field structures and pressure distributions with experimental data, it can be seen that complicated interactive flow field features are simulated correctly. The results shown that the numerical methods can be used as useful means in missile lateral control jet design.
