Abstract
In considering the existing shock wave/boundary layer interactions of the process control of supersonic inlets , based on two-dimensional plate/wedge structure, a rational Reynolds stress model ( RSM) turbulence model was used to study the turbulent boundary layer separation phenomenon by induction of an oblique shock wave impacting the flat-plate. An investigation into the wave structure of the flow field in a blowing state and the distribution of the parameters along the wall was carried out, and the impact of the blowing position and total pressure on the flow field and separation zones was analyzed. Research shows that after injecting the blowing control, the flow field parameters improve significantly. The closer the nozzle to the separation zones, the better the blowing effects, while the higher blowing total pressure is not the better one, and the best blowing pressure exists when the nozzle airflow is in a sonic condition. If confirmed, this conclusion has guiding significance for practical engineering.关键词
