Dynamic behavior of the counter-flow jet for drag reduction in hypersonic laminar flow under short penetration mode

Depending on the counter-flow jet (CFJ) injection characteristics, the flow field can be classified into the short penetration mode (SPM) and the long penetration mode. Although SPM is generally considered stable, the pressure drag coefficient exhibits significant fluctuations exceeding 10%, which cannot be explained b...
