Abstract

This paper focuses on the preliminary time-domain analysis of a multimode Wave Energy Converter (WEC), the so-called TALOS WEC, by deploying two different computational tools. The device consists of an internal sphere attached to its floater with springs and dampers, and power is captured through the sphere’s motions relatively to the floater. The equation of motion is formed based on the Cummins formulation using different calculation approaches for the convolution terms in the two tools. A comparative study, initially, is conducted assuming rigid connection of the sphere with the floater. Next, by enabling the sphere to oscillate in heave, as well as in both heave and surge, the device’s performance for one and two operational modes is assessed
