Computational Fluid Dynamics based Performance Optimisation of Vertical Axis Marine Current Turbines
Rapid decrease in the fossil fuels in the last couple of decades has stirred the researchers to find alternative sources for the production of power. Wind and tidal energies are the two most promising alternatives to the fossil fuels. While most of the recent research has been conducted on developing electro-mechanical systems for power production from wind energy, the research regarding the us...
متن کاملEntropy Current in Conformal Hydrodynamics
In recent work [1, 2], the energy-momentum tensor for the N = 4 SYM fluid was computed up to second derivative terms using holographic methods. The aim of this note is to propose an entropy current (accurate up to second derivative terms) consistent with this energy-momentum tensor and to explicate its relation with the existing theories of relativistic hydrodynamics. In order to achieve this, ...
متن کاملDevelopments in ducted water current turbines
Unlike conventional hydro and tidal barrage installations, water current turbines in open flow can generate power from flowing water with almost zero environmental impact, over a much wider range of sites than those available for conventional tidal power generation. Recent developments in current turbine design are reviewed and some potential advantages of ducted or “diffuser-augmented” current...
متن کاملHarmonic Current Predictors for Wind Turbines
The harmonic impact caused by wind turbines should be carefully investigated before wind turbines are interconnected. However, the harmonic currents of wind turbines are not easily predicted due to the variations of wind speed. If the harmonic current outputs can be predicted accurately, the harmonic impact of wind turbines and wind farms for power grids can be analyzed efficiently. Therefore, ...
متن کاملTurbidity Current Hydrodynamics and Seabed Morphology
Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...
