Response of a plate in turbulent channel flow: Analysis of fluid–solid coupling
Journal of Fluids and Structures, 2021 The paper performs simulation of a rectangular plate excited by turbulent channel flow at friction Reynolds numbers of 180 and 400. The fluid-structure interaction is assumed to be one-way coupled, i.e, the fluid affects the solid and not vice versa. We solve the incompressible Navier Stokes equations using finite volume direct numerical simulation in ...
