Abstract

Application of combined laser and microwave discharge for drag reduction at high speed is investigated. The problem is simulated as interaction of a high temperature filament with a blunt cylinder at Mach 3. The filament is initialized instantaneously in the owfild at the presence of the bow shock ahead of the cylinder. The results show the formation of a toroidal vortex subsequent to interaction of the filament with the bow shock which leads to significant drag reduction. The effect of filament length and temperature in addition to the location of filament addition on drag reduction is studied. Furthermore, the effciency and effectiveness of the system are studied. The results show that the maximum drag reduction asymptotes with higher temperatures and longer filaments.
