| 摘 要： | 采用数值方法研究了平板上超/高超声速来流与超声速横向喷流相撞引起的复杂干扰流场特性。所建立的单介质冷喷流数值模拟方法,经过了表面多方位压力分布测量结果、纹影显示的激波结构以及表面油流图谱表现的表面分离范围的实验验证。根据数值模拟与实验对比的结果,合理地描述了喷流干扰流场压力分布以及表面、空间结构特性,并分析了压力比对流场结构和特性的影响。

| Abstract: | The interaction flowfields induced by lateral supersonic single jet mounted on a flat plate had been described by numerical simulation in this paper.The method was validated by experimental results,including the pressure distributions around the jet;and schlieren photo in which the shock wave structures had been expressed;and the oil flow pattern which shown the separation region.The surface and spatial structures of interaction flowfields are revealed in detail.The influences of pressure ratio on the structures and characteristics are analyzed. |
