 Abstract

The current practice in aerodynamic design and load analysis of wind turbines is to use codes based on the Blade Element Momentum theory (BEM). These models are computationally very efficient but are limited in the physical representation of certain flow phenomena, such as yawed flow, dynamic inflow and root/tip flow, for which engineering corrections are applied. In this study the aeroelastic free vortex wake code AWSM is compared to a BEM model for a set of dynamic load cases. The aerodynamics of the global flow are solved fundamentally different: AWSM calculates three-dimensional effects intrinsically by bound vorticity on the blades and shed and trailed vorticity in the wake, whereas the BEM model requires engineering corrections for three-dimensional effects.
