RESUMO

A numerical simulation code is constructed for solving flow across a three-dimensional deformable bluff body. It has been reported by several experimental and numerical research works that compliant surface has transition delay of boundary layer and turbulent friction drag reduction effects. However, the mechanism of total drag reduction of flow across a bluff body in the critical Reynolds number regime is not clarified yet. In the present study, numerical analysis of flow across rigid and compliant cylinders in critical Reynolds number regime is performed to evaluate whether compliant surface enhance or suppress boundary layer along the cylinder surface.
