Renewable energy resources (for example, wind, solar or ocean currents, among others) possess an enormous potential, owing to the fact that they are a pollution-free and inexhaustible resource [...]

In the South Yellow Sea off the Jiangsu coast, there exists a special type of sand bodies, which are known as radial sand ridge field (RSRF). One of the characteristics of this area is the distinctive radial tidal current field. Although many studies have focused on the hydrodynamic environment around radial sand ridges, the knowledge on the genesis of the radial tidal current is still in a ver...

[1] Surface tidal circulation over the continental shelf of Duck, North Carolina, was explored using surface current observations measured by a high-frequency (HF) radar. The Ocean Surface Current Radar (OSCR) was deployed at the U.S. Army Corps of Engineers (USACE) Field Research Facility (FRF) in Duck, North Carolina, during 1–30 October 1994 and measured surface current at 20-min intervals a...

it is well known that, contaminant transportation is a major problem in coastal zones and has to be faced when coastal structures are being planned. sea pollution not only causes environmental damage, but also impacts quality and population of sea resources. oil is the most important pollutant, pollutants emanating from industries, ships, drilling and exploration in the seabed, ship sewage, tox...

Abstract This study presents results from the numerical analysis of performance Horizontal Axis Tidal Turbine under influence current various directions. The sliding mesh in ANSYS Fluent is used to simulate rotating turbine. realizable K-ε model turbulence. verified against experimental data by comparing power coefficient for velocities tidal coming zero-degree direction. After that, effects di...
