In this paper, the characteristics of the model for cryogenic high Reynolds number wind tunnel, the outline of test facilities of ETW, which a Japanese team utilized for the first time, and some test results including the Reynolds number effect are reported. These results were compared with those previously obtained in other wind tunnels and those of CFD (Computational Fluid Dynamics) analysis, and the errors between different wind tunnels were discussed., 資料番号: AA0001959011, レポート番号: NAL SP-42}, pages = {111--131}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {HOPE極低温高レイノルズ数風洞試験について}, volume = {42}, year = {1999} }
