AN OVERVIEW OF AERODYNAMIC BEHAVIOUR OF WIND TURBINE BLADE

Wind turbine is a device that extracts kinetic from wind and converts it into mechanical energy. These can only be understood with a deep comprehension of the aerodynamics. This paper focuses primarily how the blade captures wind power. The majority of the paper details the analytical approach for the analysis of aerodynamics and performance of wind turbine blades. The analysis of aerodynamic behavior of wind turbines can be started wit hout any specific turbine design just by considering the energy extraction process. Additionally, more advanced method “blade element momentum theory” (BEM) is also introduced briefly. A number of mathematical and analytical treatments have extended the kn owledge of the physics and mechanics behind the aerodynamics forces. Actually, this article outlines briefly an overview of wind turbine blade analysis based on aerodynamic forces i.e. lift force and drag force. Indeed, the design of blade according to aer odynamic requirements is crystal clear through this paper
