| Abstract | The aerodynamic thermal loads on under-expanded jet from bleed slot into a plenum are obtained at different conditions. It grossly differs from the unconfined impinging jet due to the appearance of left-confined wall. The numerical results show that at low slot angle, heat flux along impinging wall peaks twice due to the stagnation of high enthalpy flow and the shock wave/boundary layer interactions, whereas only one peak occurs at higher slot angle due to the former mechanism. When impingement angle is larger than 50°, the highest thermal loads change a little. As the impingement height increases, the overall aerodynamic thermal loads decrease at the same freestream conditions. Generally, it is the confined wall that makes the flow behind the plate shock supersonic, which allows the SWBLIs to occur. |
