Analytical Aspects of an Artificial Damping Layer for the Wave Equation

摘要

The use of damping layers is one way of absorbing water waves travelling on the211u001efree surface. In the mathematical formulation these layers are introduced by 211u001eadding certain lower order terms in the free surface equations. In this paper 211u001esome analytical aspects of such an artificial damping layer are studied by 211u001econsidering the addition of comparable lower order terms in the one-dimensional 211u001ewave equation.
