A brief description of the key issues connected with Chemical Energy Accommodation (CEA) and heterogeneous catalysis for high Mach flows is presented. Data and models are analyzed with the goal to predict CEA and its dependence on pressure and surface temperature, which are important parameters for Thermal Protection Systems design, and are also critical to predict composition of air entering an hypersonic engine. The information on the CEA available so far from simple models, is still not sufficient to draw final conclusions in regard to its behavior with pressure and temperature, even for pure metals and SiO2. Using a hypersonic CFD flow solver, a parametric analysis of the effect of varying the CEA effectiveness is presented for a nickel-coated body geometry flying in air; the consequences on body heat load and gas composition are examined. Large effects by CEA have been found for thermal loads and O atoms concentration.
