The shock wave/turbulent boundary layer interaction (SWBLI) exists widely in the internal and external supersonic flow field. The interaction of shock waves with turbulent boundary layers will induce serious separation. As a result, the flow field structure changes greatly. This leads to an increase in the flow field instability, total pressure loss, local peak heat flux, and other adverse effects. Current research shows that the secondary circulation jet control is effective in the flow field as a passive control method. In this paper, a new secondary circulation jet configuration for variable Mach number flow is designed and optimized. The flow fields of this configuration with the inlet Mach numbers being 2.5, 3, and 3.5 are studied, and an adaptive control method is proposed. For the numerical simulation of the flow field, the three-dimensional implicit Reynolds Averaged Navier-Stokes (RANS) equations coupled with the two-equation shear stress transport (SST) k-ω turbulence model are chosen. The obtained results show that when the inlet Mach number is in the range of 2.5–3.5, the secondary circulation jet configuration and the adaptive control method have positive effects on reducing the volume of the separation zone and the total pressure loss. Meanwhile, the adaptive control method can also be realized by passive control.

冲击波/湍流边界层相互作用（SWBLI）广泛存在于内外超音速流场中。冲击波与湍流边界层的相互作用会导致严重的分离。结果，流场结构发生很大变化。这导致流场不稳定性、总压力损失、局部峰值热通量和其他不利影响的增加。目前的研究表明，二次循环射流控制作为一种被动控制方法在流场中是有效的。本文针对变马赫数流动设计并优化了一种新的二次循环射流结构。研究了该构型入口马赫数为2.5、3、3.5的流场，提出了一种自适应控制方法。对于流场的数值模拟，选择了三维隐式雷诺平均纳维-斯托克斯 (RANS) 方程以及两方程剪应力传递 (SST) k-ω 湍流模型。所得结果表明，当入口马赫数在2.5~3.5范围内时，二次循环射流配置和自适应控制方法对减小分离区体积和总压损有积极作用。同时，自适应控制方法也可以通过被动控制来实现。二次循环射流配置和自适应控制方法对减小分离区体积和总压力损失有积极作用。同时，自适应控制方法也可以通过被动控制来实现。二次循环射流配置和自适应控制方法对减小分离区体积和总压力损失有积极作用。同时，自适应控制方法也可以通过被动控制来实现。
