Numerical study on the interaction of supersonic flow past a wedge and free jet

A supersonic flow past a swept or unswept ramp with the free jet ejected from the ramp end is simulated numerically employing the Piecewise Linear Method within the framework of the Euler equation. Results of simulation in the two-dimensional flow configulation predicted that a refected shock wave interacted with the free jet resulting a pressure disturbance in the flow. Results of the simulation for the swept ramp predicted that a spiral flow emerged from the ramp-side involved the free jet resulting in a pair of unified intensive vortices. This vortex stretched the fuel jet crosswise and lifted it up. Such a stretching motion of the vortex effected the increase of the contact surface of the main flow and free jet, i.e., air and fuel. Thus the effectiveness of the swept ramp injector for the mixing enhancement of fuel-air was asserted. Further studies based on the Navier-Stokes equation is necessary, which will reveal whether or not the pair of vortices is stationary.
