A turbulent separated flow over a backward-facing step is chosen for a test case where periodic perturbation is applied from its step edge. When perturbed by the most effective frequency on the reattachment promotion, the Reynolds stress is remarkably increased in the reattachment region. This increase in Reynolds stress is realized by indirect effect of applied perturbation. The details of this effect is discussed in this paper., 資料番号: AA0032827013, レポート番号: NAL SP-54}, pages = {49--52}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {周期的外乱によるバックステップ流れの制御}, volume = {54}, year = {2002} }
