Abstract
The J.-A. Bombardier Aeronautical Chair at École Polytechnique de Montréal is currently involved in a research program concerning Wind Turbines, Dynamic-Stall, Ice Accretion on Airfoils and Wings and Boundary-Layer Stability and Transition. The Chair Group, who has been engaged in the development of aerodynamic performance analysis of wind turbine machines since the 80's, has carried out a particular focus in the advanced aerodynamics applied to Vertical-Axis Wind Turbines (VAWT's). Computer codes have been developed to predict aerodynamic loads and performance of a Darrieus rotor including viscous, stochastic wind, and dynamic stall effects. Three dynamic stall models are included in our wind turbine load/performance computer codes: Gormont, MIT and Indicial models. A fundamental study of dynamic stall is presently undertaken by solving the unsteady Navier-Stokes equations. The different …
