Harnessing Tidal Energy Using Vertical Axis Tidal Turbine
An overview of the current design practices in the field of Renewable Energy (RE) is presented; also paper delineates the background to the development of unique and novel techniques for power generation using the kinetic energy of tidal streams and other marine currents. Also this study focuses only on vertical axis tidal turbine. Tidal stream devices have been developed as an alternative meth...
متن کاملEffect of rotor blade position on Vertical Axis Wind Turbine performance
In this paper a numerical study is presented with the aim of evaluating the performance output of three Vertical Axis Wind Turbine (VAWT) configurations. Here using Computational Fluid Dynamics (CFD) a two-dimensional Multi Reference Frame (MRF) approach has been used to perform steady state simulations. For this purpose an inlet velocity of 4m/s has been used along with rotor blade Tip Speed R...
متن کاملAnalysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine
In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen. According to its nominal value operational point, necessary parameters for the generator is extracted. Due to an analytical method, four generators with differen...
متن کاملNumerical Study on Self-Starting Performance of Darrieus Vertical Axis Turbine for Tidal Stream Energy Conversion
Self-starting performance is a key factor in the evaluation of a Darrieus straight-bladed vertical axis turbine. Most traditional studies have analyzed the turbine’s self-starting capability using the experimental and numerical data of the forced rotation. A 2D numerical model based on the computational fluid dynamics (CFD) software ANSYS-Fluent was developed to simulate the self-starting proce...
متن کاملComputer Simulation Studies on the Effect Overlap Ratio for Savonius Type Vertical Axis Marine Current Turbine
The Ocean has provided a new avenue in the quest for renewable energy. One potentialsource of energy is marine current, which is harnessed using either vertical or horizontal axis turbines.This paper describes a particular type of vertical axis turbine which is suitable for low current velocityapplications. The simulation of Savonius-type turbine, which hitherto has never been proposed formarin...
