This paper studies the potential for installing savonius type Vertical Axis Wind Turbine systems with the goal of maximizing the efficiency and reducing the cost. The wind turbine efficiency depends on the material of the blade, angle of the blade and shape of the blade. So material of the wind turbine blade plays an important role in the design of wind turbine. In this paper, Stainless Steel is used to design savonius wind blades of 1 m height and 0.5 m chord length with 4 different arc radii. For this purpose, CAD modeling software Solid Works is used to model savonius wind blade and static structural and modal analysis of the Stainless Steel blade is done by using ANSYS Workbench software. Static structural analysis is used to determine stress, strain, deformation and displacement under static loading condition. The response of structure for dynamic loading is determined by modal analysis. It is used to determine the natural frequency and mode shape of vibration of any structure. This wind turbine is suitable to install in small houses in urban areas.

This paper studies the potential for installing roofmounted 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.

Vertical Axis Wind Turbine

Pitch angle is one of the most important parameters of wind turbine blade. This study is aimed to investigate the effect of the pitch angle on the deformation of a VAWT. Lagrangian mechanics and Euler’s beam theory are used to derive the motion equations of linear structural vibration for straight blade vertical axis wind turbine blade with the pitch angle [Formula: see text]. The complete equations of motion take account of the 4-DOF deformation of flexural–flexural–torsion–extension as well as the material damping. Vibration analysis of generalized displacement about the equilibrium state (GDAES) is carried out with respect to the displacement of the equilibrium state (DOES), which is separated from the motion of vibration. After simplifying the equilibrium equation of 4-DOF into 1-DOF system, the exact solution of displacement [Formula: see text] of the equilibrium state is derived. The correction [Formula: see text] of [Formula: see text] due to the pitch angle and the characteristics of [Formula: see text] with constant linear speed are analyzed. Furthermore, we investigate the coupling effect of lateral bending and axial extension of the blade on [Formula: see text] is analyzed. Finally, the exact solution of [Formula: see text] is verified by the central difference method.
