Design and Analysis of a Small Scale Wind Turbine Rotor at Arbitrary Conditions (original) (raw)
This paper focuses on the works of designing a small scale wind turbine at arbitrary conditions and analyzing the structural integrity of the model via numerical simulation. The project interests are limited to geometric design of turbine blade, optimization and aerodynamic as well as structural analysis. Design of Horizontal Axis Wind Turbine (HAWT) blade particularly for low wind speed areas is of primary concern to this project. The generation of wind turbine profile is based on Blade Element Momentum theory (BEM). Design parameters like angle of attack, tip speed ratio, aerodynamic coefficients, angle of twist, airfoil profile, chord length are addressed with the aid of this theory. A three dimensional blade is then obtained by extruding the two dimensional airfoil profiles to operate at a rated speed of 5 m/s. Numerical simulations are carried out using a commercial CFD solver ANSYS CFX which reveals the flow structure and aerodynamic characteristics. The results obtained from ...
