Wave uplift on platforms or docks in variable depth.

Abstract

Incident waves were assumed nonlinear with maximum amplitude greater than the clearance between the still water surface and the underside of the platform or docks. The flow was assumed to be inviscid and irrotational without ambient current. An isoparametric mapping technique was used to transfer the fluid domain and its boundaries into a regular geometry. A Galerkin finite element model was developed to model the transformed fluid region. The resulting discrete equations were solved iteratively by using the adaptive Line Successive Over Relaxation technique. Results obtained by the numerical method were compared to the available experimental data to demonstrate the stability of the proposed algorithm.
