Abstract:The characters of interaction at large angles of attack between a lateral jet and supersonic crossflow over a slender body were simulated numerically.With the solution of a three dimensional full N-S equation which uses the HLLC approximate Riemann solver,the pressure contours of the symmetry plane,the streamlines around the the jet,and the force amplification factor Kf of the jet were described.The results show that HLLC solver has good numerical stability.The interaction reduced the effect of the lateral ...
