Title:  Water Wave Generation Techniques: Theory and Practice

Abstract: The mechanics of gravity water waves are both challenging and exciting. A comprehensive understanding of the underlying physical processes must involve a combination of (i) analytical, (ii) numerical and (iii) experimental models.

Analytical models are commonly limited in their complexity, particularly if both wave unsteadiness and wave nonlinearity are taken into account. In considering numerical or experimental modeling techniques, the fluid domain must often be constrained, may this be through solid physical walls or numerical boundary conditions. Crucially, the input boundary – the wavemaker – imposes a particular kinematics profile (or wave form).

The present seminar considers how the imposed fluid kinematics ultimately affect the quality of the investigation. In doing so, state-of-the-art wavemaking techniques for both physical and numerical wave tanks are considered. This includes active wave absorption, nonlinear wave generation techniques, and an overview of recent wave tank installations such as NSWCCD. The focus throughout will lie on the hydrodynamics of the wavemaker-fluid boundary, and how a firm understanding of this boundary may assist in the analysis of a multitude of fluid-structure interaction problems.
