Hybrid integral/quasi-steady solution of charring ablation
Abstract
Hybrid integral/quasi-steady solution of charring ablation provides very rapid, reasonably accurate predictions of carbon-phenolic response compared to finite-difference results. The new method is shown to be superior to other approximate methods with negligible run-time penalty. Additionally, the new curve-fit equations provide a very accurate, convenient description of carbon-phenolic surface thermochemistry ablation performance in air, including the effects of pyrolysis gas injection.
