Abstract

Wind turbines suffer significantly from leading edge erosion due to water droplet impacts, leading to significant loss in annual energy production. This work studies the possibility of using structured surfaces inspired by erosion resistant organisms. This is done using a combination of experiments using pulsating jet erosion testing and simulations using a coupled SPH-FEM model. Conclusions are then drawn on the impact of the various studied parameters.
