摘要
由楔/平板结构产生斜激波,入射到零攻角绝热平板上,促使可压缩层流边界层产生分离。在6°楔角的不同来流马赫数μ1下,比较了激波与边界层相互作用强度和边界层厚度等参数。得到入射激波强度是分离强弱及再附现象能否出现的主要原因,发现反射激波的状态是影响分离区范围的重要因素。
The oblique shock wave generated by wedge/plate configuration intersects the laminar boundary layer on the zero angle/adiabatic/compressible plate. With the wedge angle, the intensity of interaction and the thickness of boundary were compared due to the effect of controlling flow conditions with different Mach number. The intension of incident shock waves is the main cause of whether the phenomenon of reattachment occur or not and the range of the separation. It is discovered that the state of reflect shock wave is the crucial influencing factor of the range of separation section.
