in this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in fortran. the code was established by combining porous flow and a two-phase model using vof method. modified navier-stokes and k-ε equations implemented to the model to simulate the flow in porous media. cut cell method was modified to simulate fluid t...

The multi-chamber Oscillating Water Column (OWC) device has recently become more attractive due to its potential high efficiency. In this paper, the hydrodynamic performance of a single-, dual- and triple-chamber OWC-breakwater are investigated experimentally. first instance, quantitative comparisons implemented understand OWC-breakwaters. Specific attention been dedicated capture width ratio (...

Ultra-thin diamond-like carbon (DLC) coatings are used in hard disk drives to protect the intricate magnetic structures from wear and corrosion. The coating on the recording head consists of a hard DLC layer and a silicon (Si) layer that improves adhesion between the DLC layer and the substrate. Damage to this protective coating can expose the magnetic structures to corrosion and compromise the...

Combining wave energy converters (WECs) with a floating breakwater provides potential approach to help develop commercial-scale power operations. This paper aims design and optimize three-dimensional integrated WEC array by developing numerical model of multi-floating-body coupled system based on flow theory viscous correction in the frequency domain. By analyzing surface elevations around brea...

Abstract Way Hawang Beach, one of coastal tourist attraction, located in Village, Maje, Kaur Regency, Bengkulu Province is suffering from erosion. The regular erosion speed approximately 2 to 3 meters/year, taking the distance coastline West Sumatra Causeway which around 250 meters. Efforts eradicate abrasion on Coast are mostly carried out using protective structures. One breakwater structures...

As they have been designed to undergo colorimetric changes that are dependent on the polarity of solvents, the majority of conventional solvatochromic molecule based sensor systems inevitably display broad overlaps in their absorption and emission bands. As a result, colorimetric differentiation of solvents of similar polarity has been extremely difficult. Here we present a tailor-made colorime...

Breakwaters are characteristic maritime works and provide basic infrastructure for artificial sea land areas such as ports [...]

In this paper, a yacht project in Tingjiang Town, Mawei, Fujian, is suggested as an example of barge type breakwater made out scrap barges. The physical modelling two-dimensional flume wave test was carried on barge-type breakwater, focusing the dissipation and anchor chain forces under two different mooring methods, “crossed tilt” “front rear direct pull” mooring, with no change size breakwate...
