複数の角柱を設置した平行平板間乱流における流動構造

抄録

In the present study in order to investigate the possibility of flow control for multiple cylinders using elastic cylinder, we conduct a simulation of finite-length multiple cylinders being installed in turbulent channel flow. For a 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 multiple cylinders included elastic cylinder markedly modulates the wake structure depending on the separation between cylinders.
