Static Structural and Dynamic Properties Examination of Savonius VAWT Blades Made of Aluminum using Ansys

Abstract

This paper studies the potential for installing roof-mounted Vertical Axis Wind Turbine (VAWT) systems on house roofs with the goal of maximizing the efficiency and reducing the cost and weight of the turbine. The efficiency of the wind turbine depends on the material, shape and angle of the blade. So material of the turbine blade is an important factor in the design of wind turbine. Most of the wind turbine blades are made of mild steel and stainless steel which has more density. It has huge weight, more high corrosion and less fatigue strength. The steel can be replaced by aluminum material to reduce the weight, to improve corrosion resistance, to make them more affordable, efficient, durable and sustainable. In this paper, Aluminum material was used to design savonius wind blades of 1 m height and 0.5 m chord length with 4 different arc radii. CAD modeling software Solid Works was used to model wind blade and static structural and modal analysis of the Aluminum blade was done by using ANSYS Workbench software. This size of turbine can be most suitable for small houses in urban areas to produce electricity.
