ABSTRACT

In the present study, CFD simulation was performed for waves and currents with a 3D fixed cylinder. In order to simulate a 3D incompressible viscous flow in a numerical wave tank with a cylinder, Ansys Fluent based on the finite volume method was used in the present study. Volume-Of-Fluid (VOF) scheme is used to capture the two phase interface. In the numerical wave tank, the wave maker is controlled by the inlet boundary condition using Airy's wave theory. The outgoing wave is dissipated in an artificial damping zone at the end of the tank. The wave characteristics are inspected for different wave lengths and amplitudes. In addition, a fixed cylinder is calculated with wave and uniform current. The experimental and computed wave amplitude slightly differs as the wave steepness increases. The computed results show that the wave force increases as Froude number increases.
