Recent experiments have demonstrated the capability of microwave energy deposition for drag reduction in supersonic flows. The principal mechanism of this phenomenon is the interaction of the hot filaments generated by the microwave energy pulse with the shock system formed by the aerodynamic body. In this paper, the filament is modeled as a thin fluid region of high temperature. The interaction of the filaments with a cylindrical body in Mach 1.89 flow is examined using the compressible Euler

This study is an advancement of the simulations of pulsed energy deposition in supersonic flow performed by Farzan et al, 1 who studied the effect of varying the nondimensional filament length. The objective of this work is to investigate the effect on the aerodynamic characteristics of varying the nondimensional filament radius. A code is developed to solve the unsteady Euler equations.
