 note = {第43回流体力学講演会/航空宇宙数値シミュレーション技術シンポジウム2011 (2011年7月7日-8日. 早稲田大学国際会議場) 東京, 43rd Fluid Dynamics Conference / Aerospace Numerical Simulation Symposium 2011 (July 7-8,  2011. Waseda University, International Conference Center), Tokyo Japan, The laser absorption spectroscopy (LAS) has been applied to the high enthalpy flow at the plasma wind tunnel. However for the measurement of the arc heated air plasma it is necessary to enhance the sensitity of LAS due to its low absorbance (in the order of ca.10(exp -4)). Cavity enhanced absorption spectroscopy (CEAS) has been developed as a highly sensitive LAS method. First the CEAS is applied at a microwave discharge tube to measure the argon in the mixture gas of argon and oxygen. As a result the minimum detectable absorbance is reduced to 2.8 × 10(exp -4). Then the CEAS is applied at a 750kW Arc heated wind tunnel at JAXA. As a result in the shock layer the absorption atomic oxygen is observed and the absorbance is estimated at 5.3 × 10(exp -4)., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065207030, レポート番号: JAXA-SP-11-015},
