The surface of wind turbine blades are prone to degradation due to exposure to the elements. Rain, hail, insects are among the many causes of turbine blade degradation or erosion. Surface degradation of the wind turbine blades leads to a reduction in the aerodynamic performance, resulting in power losses. The effect of surface degradation is...

Surface degradation of the wind turbine blades lead to a reduction while on the other hand blade add-ons like, vortex generators, lead to an increase in the aerodynamic performance. Within this study, both the reduction due to leading edge roughness and the increase due to vortex generators in the aerodynamic performance are quantified...

Innovations in leading edge protective wraps or protective coatings are currently being developed to counter the effects of leading edge erosion and damage on wind turbine blades. Concurrently, the design and development of vortex generators (VGs) is taking place to counter aerodynamic stall and enhance the aerodynamic performance of wind...

Within this study an unsteady, two-dimensional interacting boundary layer method is presented for the incompressible flow around wind turbine rotor blade sections. The main approach is to divide the flow field in to two regions; the one in the vicinity of the surface where the viscosity is e effective (so called boundary layer) and the one away...
