0124 柔軟構造体を設置した平行平板間乱流の流動特性(OS1 噴流,後流および剥離流れ現象の探求と技術革新,オーガナイズドセッション)
詳細
In the present paper in order to investigate the possibility of flow control using elastic body, we conduct a simulation of a finite-length square cylinder placed inside turbulent channel flow. For an elastic cylinder, the rigorous equation of motion for elastic continuum is solved with a finite volume method; the effect of existence of cylinder in the flow computation is taken into account using the immersed boundary method. From time averaged quantities, we demonstrate that the flow pattern around rigid cylinder is in accordance with that of previous reported experimental results and that the elastic cylinder markedly modulates the wake structure, u
