Study of a Vertical Axis Wind Turbine with Deflection Panels: COMSOL 2D Simulation of a Single Panel
Keywords:
Wind Energy, Vertical Axis Wind Turbine, COMSOL Simulation, Renewable EnergyAbstract
This paper presents a simulator based study of the energy output potential of a Vertical Axis Wind Turbine (VAWT) with deflection panels. The specific turbine of this study consists of panels arranged so that each panel is vertical (perpendicular to its travel direction) and thus fully exposed to the wind stream when it travels downwind, and is flipped to a horizontal position (parallel to its travel direction) when it travels upwind. The contribution of this study is the understanding of the energy production potential for this type of VAWT. Due to the complexity of the fluid flow involved, Computational Fluid Dynamics (CFD) models based on the COMSOL Multiphysics® simulation software package have been built to estimate the energy output that can be achieved with an actual physical implementation of this turbine. The modelling and the data obtained from the simulations are presented in this paper.
