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.
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.
