Abstract
In this study, a mixed CFD (Computational Fluid Dynamics) and BEM (Blade Element Momentum Method) analysis is implemented for simulating the flow field around a wind turbine rotor to predict its aerodynamic performance such as the Power Curve diagram and the forces and moments imposed on the rotor blades that are essential in structure design of wind turbine. The present approach requires considerable less computational time and memory than three-dimensional simulation of a wind turbine rotor by merely CFD methods. This work consists of two parts: 1Calculating 2D aerodynamic coefficients of the blades by CFD methods, using Fluent commercial software. 2-Simulating 3D flow field through the wind turbine rotor using BEM technique. To validate the current approach, the numerical results is compared with experimental. The numerical results indicate good accuracy with those of experiments.
