The thermo-chemical nonequilibrium Navier-Stokes analysis shows that HCN is efficiently produced in the stagnation region and transported into the atmosphere by the wake flow. To simulate such process experimentally in the hypersonic air flow of the wind tunnel, the experimental model composed of the ablative nose part made from water ice and dry ice to supply the C and H elements and the after-body having the electric discharge circuit in it to supply the energy necessary for chemical reactions has been designed, based on the CFD results. We observed the emission from CN in the wind tunnel, and better understanding about the phenomena is expected by comparison with the CFD analysis., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062070024, レポート番号: JAXA-SP-13-001E}, pages = {295--305}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Wind Tunnel and CFD Studies on Production of Prebiotic Materials in Hypersonic Flow around Extraterrestrial Entry Object}, volume = {JAXA-SP-13-001E}, year = {2013} }
