Computational Modelling of Velocities and Accelerations in Steep Waves

Skourup, J. / Jonsson, I. G. / Grilli, S. T. / Svendsen, I. A.

Abstract The Boundary Integral Equation Method is used for the spatial solution of a non-linear, periodic water wave problem. The temporal updating of the free water surface is performed using the exact non- linear free surface boundary conditions. A method for updating water particles in the interior of the fluid domain enables one to follow the particle motion as the wave propagates in time. A structure is introduced in the computational domain, and its influence on the particle trajectories is visualized. The computational model presented here is two-dimensional, but there are (in principle) no limitations for the model to be extended to three spatial dimensions.
