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...

an oral sustained-release floating tablet formulation of metformin hcl was designed and developed. effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and hpmc-peo polymer combination, respectively. tablet composition was optimized by response surface methodology (rsm). seventeen (17) trial formulations were analyzed according to box-behnken desi...

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...

Abstract The awareness of the energy and climate crisis has accelerated development renewable sources. Photovoltaic (PV) solar power plants harvest clean convert it to electricity, which will be one most promising alternatives industry in context a low-carbon society. Due its low density, traditional deployment PV systems on land or inland rivers requires much space. Therefore, industries are i...

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...
