Abstract

A simple computational approach is presented that models the laser-induced heating of a flat-plate target, including convective heat transfer for atmospheric flight conditions up to a Mach number of 4. The results of the computational model are shown to compare well with time-resolved experimental measurements of the temperature distribution in laser targets in high-speed flows. The numerical results are nondimensionalized and compared with analytical solutions to determine general guidelines for the conditions in which convective heat transfer can be expected to have a significant effect on laser heating of typical aerospace materials.
