Abstract
In this work, temperature fields and heat fluxes under the action of a pulsed point heat source are studied based on the analytical solution found for the first time to the problem of heat transfer in the anisotropic space with absorption with temperature-dependent characteristics. It is found that the heat transfer is of the wave type and the thermal-wave fronts have the shape of ellipses in a plane. Thermal energy sinks are taken into account, and thermal disturbances are localized inside an ellipse even when time tends to infinity. The results confirm the hypothesis of the localization of fronts of thermal disturbances and heat fluxes in heat-shield composites during their phase transformations under conditions of aero-gas-dynamic heating.
