| 摘 要： | 研究了旋成体上超声速来流与超声速横向多喷流相撞产生的层流干扰流场特性. 数
值方法针对三维可压缩Navier-Stokes方程按二阶精度Roe格式进行离散，采用基于多区对
接网格技术的有限体积法. 数值模拟结果描述了多喷流干扰流场的空间结构以及激波/边界层
干扰引起的分离范围，探讨了沿流向等间距排列的喷口个数对表面和空间流场结构以及压力
分布的影响规律. 结果表明，第一喷口对多喷流干扰流场主要结构和喷口上游表面分离范围
起主导作用. 其中三喷流流场数值模拟的对称面激波结构与实验纹影结果进行对比，符合较
好.

| Abstract: | Transverse jet technology has been applied to many aircrafts as an effective way of attitude control. It can provide thrust more rapidly and is affected by less flight conditions than conventional aerodynamic surface control.Therefore,the maneuverability of the aircraft is enhanced.And less aerodynamic surfaces are needed, thereby the weight is reduced and the stealth performance is improved.Recently,the method of jet attitude control is paid more and more attentions. When a sonic or supersonic jet is injec... |
