To share the construction and maintenance cost, an asymmetric oscillating water column (OWC) device integrated with a pile-fixed box-typed offshore breakwater is considered experimentally numerically. A fully nonlinear numerical wave tank established validated open source solver OpenFOAM. The effects of width draft rear box, incident height on energy conversion efficiency, reflection transmissi...

This paper presents the results from a numerical simulation study to investigate wave trapping by series of trapezoidal porous submerged breakwaters near vertical breakwater, as well seabed response around breakwater. An integrated model, based on volume-averaged Reynolds-averaged Navier–Stokes (VARANS) equations is developed simulate flow field, while dynamic Biot’s are used for simulating wav...

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...

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...

Estuarine shorelines have been degraded since humans arrived in the coastal zone. In recent history, a major cause of habitat degradation has been the armoring of shorelines with vertical walls to protect property from erosive wave energy; however, a lack of practical alternatives that maintain or enhance ecological function has limited the options of waterfront residents and coastal zone manag...
