Abstract: The integration of wave energy converters within breakwaters is a promising application towards coastal protection and energy generation. Housing a pneumatic chamber for wave energy extraction in breakwaters can enhance their shoreline protection function without significant additional construction costs. This study will assess the efficiency of fixed, heaving and floating breakwaters with and without OWC integration. Their potential to protect the coastal zone is quantified by estimating relevant wave reflection and transmission coefficients. This is in combination with the assessment of their potential to harvest wave energy. The latter will be considered by measuring the pressure and the surface elevation fluctuations inside the modelled OWC. In this seminar, I would like to introduce my PhD project, talk about experimental challenges, and introduce a proposed solution to the problem of the incident and reflected wave amplitudes decomposition incorporating the dissipation effect.
