Numerical and experimental investigation of free surface gravity waves is performed in comparison. Based on the potential flow assumption and fully nonlinear boundary condi- tions, a numerical wavemaker reproduces the experimental environment and allows for a combined detailed analysis of the relevant effects. A boundary integral formulation and a subdomain decomposition are used to provide high computational efficiency. The propa- gation of a regular wave with increasing steepness is analyzed by comparing the numerical results with the experiments performed.

Abstract

Numerical and experimental investigation of free surface gravity waves is performed in comparison. Based on the potential flow assumption and fully nonlinear boundary condi- tions, a numerical wavemaker reproduces the experimental environment and allows for a combined detailed analysis of the relevant effects. A boundary integral formulation and a subdomain decomposition are used to provide high computational efficiency. The propa- gation of a regular wave with increasing steepness is analyzed by comparing the numerical results with the experiments performed. Finally, the generation of a wave packet is briefly reported both through the numerical and the experimental results.
