Blade design and optimization of a horizontal axis tidal turbine
Ocean Engineering, 2020Tidal turbine is a device which converts the kinetic energy of water into electric energy. The blade element momentum theory (BEM) is used to design the blade in this paper.

Micropower From Tidal Turbines
Volume 1B, Symposia: Fluid Machinery; Fluid Power; Fluid-Structure Interaction and Flow-Induced Noise in Industrial Applications; Flow Applications in Aerospace; Flow Manipulation and Active Control: Theory, Experiments and Implementation; Fundamental Issues and Perspectives in Fluid Mechanics, 2013In addition to utility-scale power generation (e.g., rated capacities greater than 106 W), there are also possibilities for tidal current generation at the micro-scale (e.g., rated capacities less than 102 W) that could provide power to autonomous oceanographic instrumentation. This paper presents performance characteristics of a high-solidity, helical,

This study presents a model to analyse and simulate tidal power generation for hybrid power system in the presence of highly infiltrated tidal units. The response of the hybrid system may be at risk without suitable frequency enhancement techniques.

Renewable Energy, 2014
Abstract During the last decade, the development of tidal current industries has experienced a rapid growth. Many devices are being prototyped. For various purposes, investors, industries, government and academics are looking to identify the best device in terms of of cost of energy and performance.

The efficiency of a turbine in a tidal channel
Journal of Fluid Mechanics, 2007There is an upper bound to the amount of power that can be generated by turbines in tidal channels as too many turbines merely block the flow. One condition for achievement of the upper bound is that the turbines are deployed uniformly across the channel, with all the flow through them, but this may interfere with other uses of the channel. An isolated

Implementation of Tidal Stream Turbines and Tidal Barrage Structures in DG-SWEM
Volume 10: Ocean Renewable Energy, 2019Abstract There are two approaches to extracting power from tides — either turbines are placed in areas of strong flows or turbines are placed in barrages enabling the two sides of the barrage to be closed off and a head to build up across the barrage.

Tidal Current Turbine, Wind Turbine and Their Dynamic Modelling
2014Wind and tidal current are of the most common energy resources for generating electricity in the near future because of the oil problems (crises and pollution). Within that frame, wind and tidal current energies are surging to the fore. The dynamic model of the offshore wind and tidal current is very important topic for dealing with these renewable ...

Tuning turbines in a tidal channel
Journal of Fluid Mechanics, 2010As tidal turbine farms grow they interact with the larger scale flow along a channel by increasing the channel's drag coefficient. This interaction limits a channel's potential to produce power. A 1D model for a tidal channel is combined with a theory for turbines in a channel to show that the tuning of the flow through the turbines and the density of ...
