Instantaneous views of the single turbulent spot gave a quite different image from the ensemble averaged one, being composed of several small scale velocity defect and excess regions. These regions were elongated in the streamwise direction and alternately arranged along the leading edge of the spot. When the two spots were simultaneously generated, their wing tips came to overlap each other as they grew downstream and the velocity defect regions at each wing tip were superposed. Then, a far stronger velocity defect region was generated there., 資料番号: AA0001655006, レポート番号: NAL SP-40}, pages = {21--24}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {乱流斑点の相互干渉に関する実験的研究}, volume = {40}, year = {1999} }
