Transport Model for Condensing Pyrolyzing Species within Porous Material

Current material response codes are limited and do not have the capability of capturing all physical phenomena found within a charring ablator. One such phenomena, thermocouple hump, is present in a multitude of experimental data and has hindered the reconstruction of the surface temperature for Exploration Flight Test 1. Water content within the TPS has been hypothesized as the main contributor to this phenomena. The provided proposal will set forth a detailed framework in which a high fidelity multiphase H2O model within the ablation material can be built upon.
