Application of an Immersed Boundary Method to Simulating Turbulent Flow Around a Floating Body

초록

We propose application of an immersed boundary method to simulating flow around a floating body. An immersed boundary method facilitates implementation of a complicated body shape on a Cartesian grid system. Marker particles are used to transfer the complex geometrical information to the solver. A volumeof-fluid method and a LES modelling with a Lagrangian dynamic subgrid scale model are also incorporated to resolve the motion of the free surface and the turbulent eddies, respectively. In this presentation, we will demonstrate the effectiveness of the immersed boundary method we adopted, by presenting the simulation results of the flow around a floating body of complex shape.
