Abstract
AbstractThis study presents to investigate the mechanical properties and thermal properties of horizontal and vertical axis wind turbine (VAWT) blade using finite element analysis (FEA) Ansys software. The efficiency of the wind turbine is based on the design of wind turbine blade (WTB) and material used. The fiber-reinforced plastics (composite materials) such as glass fiber, carbon fiber and epoxy are used for model of wind turbine blade. After modeling of wind turbine blade using standard software CATIA, imported into software ANSYS for determining the structural and thermal strength of the wind turbine blades. The stress distributions observed on the horizontal axis wind turbine blade due to the applied structural load and thermal load. The maximum stress occurs on the surfaces (near the fixed end of hub) of the horizontal axis wind turbine blade (HAWT), and the minimum stress occurs near the tip end of the blade. Due to the applied thermal condition (temperature) on the blades, the heat flux generated almost equal to both the HAWT blade and VAWT blade. Based on the FEA Ansys results, horizontal wind turbine blade produces better structural strength and thermal strength than vertical wind turbine blade.KeywordsWind turbine bladeFinite element analysis (ANSYS)Composite materialsStrength propertiesThermal properties
