要約

The conduction of heat inside solids involving a process of ablation is of interest in the field of aerospace engineering. The solution to this kind of problem, which involves heat transfer and phase changing, shows some special difficulties, mainly due to the moving boundaries. Heat transfer by ablation in different geometries submitted to transient boundary heat flux is studied analytically. In this paper the Integral Transform Technique and the Generalized Integral Transformed Technique are applied for the solution of equations for the preablative and the ablative phases, respectively. The results of interest are the ablation depth and the speed of the moving boundary.
