Analysis of NACA 0020 aerofoil profile rotor blade using CFD approach

Abstract

Impact of aerofoil blade design and their selection is one of the significant parameter in power generation using Savonius Vertical Axis Wind Turbine. Vertical Axis Wind Turbine (VAWT) is designed to fulfil human needs. In terms of total cost from an environmental standpoint, it is moderately very cheap when compared to current conventional methods. Kinetic energy, or wind velocity, is used to generate electricity by modifying mechanical energy, which is abundant and limitless. There would be no pessimistic impacts on the environment if such classifications were used. This method is superior to other conventional ways because the upkeep and operating costs are minimal. The principle reason behind the study is to evaluate the performance of a Savonius types Vertical Axis Wind Turbine (VAWT) on a NACA 0020 aero foil profile blade at various wind speeds, solidity ratio using CFD Analysis. The blade is designed to have a 00 angle of attack and a curvature of 150 on blade profile. Output power is calculated at variable speeds based on the speed of the rotor and the power available in the wind.
