The current chapter presents wind-energy simulations obtained with the vortex code OmniVor (described in Chap. 44) and compared to BEM, CFD and measurements. The chapter begins by comparing rotor loads obtained with vortex methods, BEM and actuator-line simulations of wind turbines under uniform and yawed inflows. The second section compares wakes and flow fields obtained by actuator-disk simulations and a free-wake vortex code that uses vortex segments and vortex particles. The third section compares different implementations of viscous diffusion models and investigate their effects on the determination of wake deficits. The last section compares the wake deficits obtained from vortex code and CFD simulations under turbulent conditions with results from lidar measurements.
