The instantaneous velocity fields induced by a vortex ring were measured by employing the PIV (Particle Image Velocimetry) in which the cross correlation method was used. The time evolution of velocity vector fields during the impingement was shown., 資料番号: AA0028636011, レポート番号: NAL SP-47}, title = {地面に衝突する渦輪の速度場}, year = {2000} }
