A plate-wave energy converter (pWEC) moored in front of a floating stationary breakwater is considered. The pWEC composed submerged flexible plate with piezoelectric layers bonded to both faces it. Hence the elastic motion excited by water waves can be transformed into useful electricity due effect. To evaluate performance breakwater-attached terms wave power absorption and attenuation, hydroel...

Breakwaters are the important and the costly ones of the marine structures. Composite breakwater is one of the common types in the world. Because of the sensitivity of composite breakwaters to environmental conditions, also construction costs, difficulty of repair and maintenance and importance of equipments on and behind the breakwater, design of composite breakwater must be very accurate. Goa...

In the present study, hydrodynamic efficiency of a cylindrical wave energy converter (WEC) vertical symmetry axis and arranged in front reflecting orthogonal breakwater is explored. The idea based on exploiting anticipated amplification scattered reflected fields originating from presence walls, towards increasing WEC’s power absorption due to walls’ reflections. Two types converters are examin...

A small-scale field experiment was conducted on a U-OWC incorporated into caisson breakwater at the NOEL laboratory of Reggio Calabria (Italy). The U-Oscillating Water Column (U-OWC) or REWEC (REsonant Wave Energy Converter) is device belonging to family OWCs. Such very innovative, being able absorb high percentage incoming sea waves energy and produce electrical power via proper PTO. focus pap...

The study examines the influence of a sloping porous bed on efficiency an oscillating water column (OWC) device facing oblique waves. A vertical, surface piercing, thin plate near rigid wall approximates OWC. system is simulated using multi-domain boundary element method assuming linear potential theory. impact varying structural parameters and incident wave angle performance OWC evaluated disc...

We model regular and irregular design waves of interest in coastal ocean engineering, using a Numerical Wave Flume (NWF) based on Moving Particle Semi-Implicit (MPS) method. A key feature the is implementation new scheme for artificial viscosity, which original to Smoothed Hydrodynamics (SPH) method here formalised into MPS context. In addition, we complement NWF with wave generator dynamic bou...

The effect of a detached breakwater, which was constructed to improve harbor tranquility inside Pohang New Port, examined through the comparison wave data measured before and after construction breakwater. observation showed that energy effectively reduced by although height outside breakwater higher its construction. in all wave-propagating directions, but it also observed became less effectiv...
