The effects of surface-chemistry processes of a graphite sample exposed to a subsonic high-enthalpy nitrogen flow are investigated using a coupled computational fluid-dynamics/surface-chemistry model. The results obtained are assessed for the accuracy of the model using experimental data from tests conducted in a 30 kW inductively coupled plasma torch facility at the University of Vermont. Significant discrepancies are observed between the computational and experimental results. Therefore, a study is performed to determine sensitivities of flow and surface parameters to variations in testing input conditions, as well as physical modeling parameters. Measurements of the absolute number density are required to draw firm conclusions about the surface-chemistry models, as well as the surface reactions involved.
