It produces quantitative pressure data. The PSP was estimated its performance as a CFD validation tool in this paper. At first, overview of PSP and PSP development at JAXA were described. PSP and CFD data of ONERA M5 model, which is a standard model of transonic wind tunnels, were used to compare with each other. The PSP test of ONERA M5 was conducted at JAXA 2 m x 2 m Transonic Wind Tunnel. Its test condition used in PSP/CFD comparison was M = 0.84, Alpha = 0 deg, P0 = 100 kPa. The PSP results were quantitatively in good agreement with pressure tap data and also good agreement with CFD data globally. There were 3 different regions between PSP and CFD data. Those regions were graphed and their possible reasons were considered. PSP and CFD data comparison on several arbitrary lines on test model were also demonstrated. It could be clear up the discrepancies between PSP and CFD data and the difference between PSP and pressure tap measurement. Then the superiority of PSP data was estimated comparing with pressure tap measurement. It is considered that PSP has large potential as CFD validation tool because it has large quantitative pressure information similar to CFD data., 資料番号: AA0048469031, レポート番号: JAXA-SP-04-012}, pages = {184--189}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {感圧塗料計測データを用いたCFDコード検証について}, volume = {JAXA-SP-04-012}, year = {2005} }
