Abstract
The effect of microwave and laser “heat spots” on a supersonic flow past a hemisphere-cylinder and a hemisphere-cone-cylinder at Mach 2.1 to 3.45 is studied. Drag forces are evaluated for the known experimental data on stagnation pressure dynamics. The energy deposition by laser and microwave discharges in the oncoming flow is approximated by heated rarefied layer/layers (“filaments”). Approaches for decreasing the frontal drag force for the considered microwave and laser experiments are suggested. Complex conservative difference schemes are used in the simulations.
