Absorbing boundary conditions for water wave simulation in the vicinity of a solid body

Abstract : In this paper, we focus on the modelling of the wake of a solid body moving through a body of water. To this end, the flow of an in-viscid, barotropic and compressible fluid around the solid body regarded as motionless is examined. The dynamic behaviour of the fluid is analysed by means of a two-dimensional Neumann-Kelvin's coupled model enhanced with capillarity and inertia terms. For computational purposes, the unbounded spatial domain must be truncated by artificial boundaries. Difficulties arise when it comes to setting appropriate absorbing boundary conditions for a waves propagation problem in a stratified convective fluid media with significant differences between layer properties. Numerical illustrations of the results are given and commented.
