SHTP-E, A Computer Implementation of the Finite-Difference Embedding Method of Ablation Analysis.
Abstract
PL/I procedures have been developed that use finite-difference techniques to analyze ablation problems by embedding them in inverse heat-conduction problems with no moving boundaries. The procedures form a set of subroutines that can be called from a problem-oriented main program written by the user. The procedures include provisions for one-, two-, or three-dimensional conduction, parallel modes of heat transfer, thermal contact, choices of implicit- and explicit-difference techniques, temperature-dependent and directional thermal properties, radiation relief, aerodynamic heating, chemical ablation and material removal from combinations of flat, cylindrical, and spherical surfaces. This report is meant to serve as a source of underlying theory not covered elsewhere and as a user's manual for PL/I procedures. Also included are useful debugging aids and external identifiers, a directory of Applied Physics Laboratory computer libraries pertaining to the PL/I procedures, and an illustrative problem as an example.
