Presentation Abstract

Wind energy is an attractive source for electricity because it generates minimal greenhouse gases and no pollution when in operation. Harvesting energy from wind turbines and their mechanical efficiency depends on its blades geometry. The common blades are configured using classical airfoil theory. We investigate the potential utilization of nonlinear swept blade geometry as a mean to increase efficiency. The nonlinear swept blade is inspired by the swift bird who can fly continuously for 10 months nonstop. In this study, a new wind turbine blade, inspired by the nonlinear swept configuration of the swift bird wings, is tested and compared to a linear swept blade. The turbines wake region were measured using Particle Image Velocimetry (PIV) in a flume. PIV provides the spatial distribution of instantaneous velocity fields at the wake. The wake flow dynamics were analyzed and compared providing a benchmark to evaluate the performance of nonlinear swept blades.
