内容記述 | 2次元数値シミュレーションを使って種々の迎角をもつ2次元翼NACA0012上の剥離流に及ぼす音響加振の効果を検討した。結果は、2次元シミュレーションでも、適切な周波数を用いた音響加振が前縁剥離を力学的に抑制することを示した。これらの現象は、吸込み面上の層流剥離点近傍の渦度構造ならびに剥離流領域における渦度構造の変化に関係している。 | |||||

内容記述 | The effect of acoustic excitation on the separated flow on the Two-Dimensional (2D) airfoil NACA0012 with various angles of attack is investigated in 2D numerical simulation. The results show that the acoustic excitation with appropriate frequency dynamically suppresses the leading edge separation even in 2D simulation. These phenomena are related to a change of vorticity structure near the laminar separation points on the suction surface as well as that in the separated flow region. | |||||
