The accuracy of airfoil polar predictions is limited by the usage of imperfect turbulence models. Can machine-learning improve this situation? Will airfoil polars teach the effect of turbulence on skin-friction? We try to answer these questions by refining turbulence treatment in

The objectives of this paper are to investigate the feasibility of a 10 MW generator for a direct-drive wind turbine and to compare the generator systems for pitch control and for active speed stall control. The idea behind the active speed stall control concept is to make a roto

The objective of this paper is to assess 10 MW directdrive permanent-magnet (DDPM) generator systems with different control strategies namely pitch control and active speed
stall control. In the active speed stall control concept, there is no pitch mechanism, and the rotor speed
