Abstract
The unsteady aerodynamics computational fluid dynamics simulations of the flow-field around a three-bladed Rutland 503 horizontal axis wind turbine rotor have been conducted in this paper to provide information needed to predict the three-dimensional aerodynamics behavior. In the CFD analysis, the variation of wind velocity between 9.3m/s and 15m/s is investigated. The Detached Eddy Simulation method is used with the turbulence model SST. A multiblock structured mesh is used for the discretization of the study domain. The solutions are obtained by using the Solver Fluent 6.3 which uses the method of finites volumes. The results of simulations obtained are compared with the experimental data [1] obtained in Wind Tunnel Laboratory LMA Arts and Metiers Paris-Tech in order to validate these results. Results of the numerical simulation in three dimensions of the unsteady field of flow around the blade are presented.
