Numerical Studies of Directional Wavemaker Performance

Abstract

The performance of a multi-unit wavemaker for generating directionally-spread waves has been studied using the three-dimensional, radiation-diffraction code WAMIT. Design choices of wavemaker geometry (including type of motion, total number of units and size of individual units) affects various parameters of performance, including quality of radiated waves and inertial load that actuators must overcome. The sensitivity of generated waves to these variables is demonstrated.
