A Self-adaption Wave Absorbing Method with Porous Media Model in Numerical Wave Tanks

摘要

A two dimensional numerical wave tank (NWT) based on the Navier-Stokes equations for viscous, incompressible fluid and VOF method is established. The momentum source method is employed to generate the wave. A self-adaption wave absorbing method based on the porous media model, which can vary as the local flow field, is proposed. The results shows that the self-adaption wave absorbing method can dissipate the wave energy effectively.
