Boundary Conditions for 2D Boussinesq-type Wave-Current Interaction Equations
Abstrac t : This research focuses on the development of a set of two-dimensional boundary conditions for specific governing equations. The governing equations are existing Boussinesqtype equations which is capable of simulating wave-cmrent interaction. The present boundary conditions consist of for waves only case and for ctm:ents only case. To simulate wave-cmTent interaction, the two kinds of the present boundary conditions are then combined. A numerical model based on both the existing governing equations and the present boundary conditions is applied to simulation of cmTents only and of wave-cm·rent interaction propagating over a basin with a submerged shoal. The results of the numerical model show that the present boundary conditions go well with the existing Boussinesq-type wave-cmTent interaction equations.
Keywords : Boundary condition, Boussinesq, wave, cmTent, free sm-face.
