SKIMMER - A Numerical Model for Nonlinear Waves.
Abstract
The calculation on nonlinear free surface waves produced by a moving disturbance on a free surface was studied using a time-dependent numerical model. Two frames of reference were tried in making the calculations, one fixed to the surface disturbance, and the other fixed to a laboratory reference frame. Verification studies were performed which indicate the model is capable of accurately reproducing both linear and nonlinear wave profiles, in either frame of reference. However, calculations, in which the disturbance was assumed to be fixed with the fluid streaming past it, were found to be more efficient in terms of computer storage and time. (Author)
