Abstract

Characteristics of thermal waves emanating from a fast-moving heat source are studied in this paper. The heat source is assumed to occupy a finite region to model real situations in local heating. Analytical solutions are obtained respectively for a heat source moving in the subsonic, transonic, and supersonic regimes. The Green’s functions obtained previously from a point source are used to generate temperature distributions for all cases. The temperature jump across the shock surface is found to be weaker than the case with a point heat source, while the swinging phenomenon for the temperature variations with the thermal Mach number still exists.
