The experiments were carried out under airflow velocity of 1.6 m/s and Goertler parameter of about 40. The behaviour of the vortices was taken using new moving smoke-wire method with Strobo vision scope. Furthermore, the mean velocity, turbulent intensity and velocity gradient were also measured, and these distributions were compared with the behaviour of the vortices., 資料番号: AA0004172013, レポート番号: NAL SP-25}, pages = {43--46}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {凹曲面に沿う馬蹄形渦崩壊過程の可視化}, volume = {25}, year = {1994} }
