Abstract
- 感圧塗料（Pressure-Sensitive Paint :PSP）計測はこれまで1kPa～500kPaの圧力レンジで利用され，風洞において航空宇宙機モデル上の圧力場計測が行われてきた．本研究では，PSP計測技術利用拡大に向けて，高Kn（Knudsen Number, Kn）数流れへの適用可能性を調べるため，超低圧力レンジでの圧力感度特性を評価した．本レポートではその結果について報告する．<br />Pressure-Sensitive Paint (PSP) technique has been developed for acquiring surface pressure images on a model in the wind tunnel tests. Generally, PSP measurement has been conducted with a pressure range from 1kPa to 500kPa. In this study, the characteristics of PSP in the ultra low pressure range (10(exp -3) - 10(exp 2) Pa) were evaluated for visualization of high Knudsen (Kn) number flowfields.<br />形態: カラー図版あり<br />Physical characteristics: Original contains color illustrations
