NUMERICAL INVESTIGATION OF THE AXISYMMETRIC INTERACTION BETWEEN COMPRESSIBLE STREAMWISE VORTICES AND SHOCKWAVES 1)

Numerical results on the interaction between the compressible streamwise vortices and shockwaves were presented in this paper.Two cases were discussed including a moving shockwave interacting with a vortex and a Mach disc at the exit of an overexpanded nozzle interacting with the vortex in the swirling jet. The quasi axisymmetric N S equation was used and the time accurate finite difference TVD scheme was implemented. Compared with the corresponding experiments, the numerical simulat...
