Probability values of nitridation reaction are determined from the amount of mass loss of graphite test piece and atomic nitrogen density in the test section. The amount of atomic nitrogen is determined by calculating the flowfield around the graphite test piece under wind tunnel freestream condition. The freestream condition at the entrance of test chamber is evaluated by calculating the flows in the plasma torch fully theoretically. It is found from experimental and numerical results that the reaction probability is about 0.003 for the surface temperature of about 1,900 K. The uncertainties in the results are also described, and improvements are proposed., 資料番号: AA0063824015, レポート番号: JAXA-SP-07-008E}, pages = {150--157}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Experimental and numerical study of surface nitridation of thermal protection material}, volume = {JAXA-SP-07-008E}, year = {2008} }
