To determine the exciting frequency of the synthetic jet, this paper presents the stability analysis of the separating shear layer downstream of the step. The Reynolds number based on the step height ranges from 133 to 3670. The results show effectiveness of the synthetic jet for flow control. The reattachment length on the lower wall decreases due to the vortices which are generated by the synthetic jet with the exciting frequency., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064575002, レポート番号: JAXA-SP-09-014}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {低レイノルズ数域後方ステップ流れの不安定解析を用いた制御}, volume = {JAXA-SP-09-014}, year = {2010} }
