Aerotherm Graphite Surface Kinetics Computer Program (GASKET2) User's Manual

Abstract

The Aerotherm GASKET code was modified. The modified code, entitled GASKET2, includes a generalized computational scheme for combined equilibrium - nonequilibrium systems, sublimation kinetics, and an expanded thermochemistry data bank including the Duff-Bauer hydrocarbon species. GASKET2 predicts higher ablation rates than GASKET at surface temperatures above 5500 R. Both codes predict virtually equal rates at surface temperatures below 5500 R. GASKET2 also accepts an increased number of surface kinetics - controlled reactions. In addition to the modifications, surface kinetics for ATJ and G-90 bulk graphites, 15% silicon carbide modified pyrolytic graphite and pyrocarb 901 and Carbitex 700 carbon/carbon materials were added to GASKET2. Also, improved surface kinetics for C plane pyrolytic graphite were included.
