Investigation on the three-dimensional shock wave/turbulence boundary layer control induced by the secondary recirculation jets

Abstract

The interaction between the shock wave and the turbulence boundary layer induces a separation, and this is an undesired phenomenon for the flow field performance. The control work of the separation is pretty important. In the current study, the passive control is carried out. The three-dimensional coupled with the implicit Reynolds Averaged Navier-Stokes (RANS) equations and the two-equation shear stress transport (SST) k-ω turbulence model have been used to simulate the shock wave/boundary layer interaction (SWBLI) flow control induced by the secondary recirculation jet numerically. Four different configurations of the secondary recirculation jet device are put into investigation. The obtained results show that the control induced by the secondary recirculation jet has pretty good effect to decrease the projected area and the volume of the separation zone, as well as the wall heat flux. The projected area and the volume can be reduced by 24.68%.and 29.31%, respectively, and the wall heat flux can be reduced by 17.92%. The case with the best effect equips with two blow or bleed holes and proper spacing. The high heat flux distribution is closely related to the reattached node.
