| 摘 要： | 采用AUSMDV迎风格式空间离散三维定常可压缩NS(Navier-Stokes)方程组,数值模拟了带有横向超音速喷流的尖拱弹体流动。分析了干扰流场涡结构、波系结构以及干扰流场对弹体气动特性的影响,给出了物面极限流线图谱。结果表明,喷流上游的高压区与下游的低压区产生附加的气动力,将物面压力分布与试验结果进行比较,二者具有较好的一致性。

| Abstract: | The lateral jet interaction in supersonic flow was simulated numerically by solving Navier-Stokes equations with CFD solver.The AUSMDV scheme was adopted to deal with the governing equations.The vortex and wave structures were studied and the topology of separation flow was given according to the CFD results.The CFD results agree well with experiment values. |
