Performance evaluation of wave-carpet in wave energy extraction at different coastal regions: an analytical approach

Abstract

Globally, muddy seafloors have been reported to extract a significant percentage of energy in wave that interacts at different wavelengths. Since mud is capable of taking so much energy out of ocean waves, the researchers are planning to use this incredible concept to design an efficient Wave energy converter. They have proposed an idea of creating a viscoelastic carpet for Wave Energy Conversion (CWEC) mounting on coastal floors through a network of vertically oriented some springs and generators, which should extract wave energy exactly in the same way as the muddy seafloor does. Dynamic ripples and undulations can be induced on the surface of its spring and electrical power produced by these perturbations. This paper presents an analysis of performance of a mud-resembling carpet in harvesting ocean wave energy for multiple sea states in different countries. In addition, a brief on energy extraction using wave carpet technology for various locations with varying water depth and some recommendations for future studies are specially highlighted.
