SYSTEM OF ACCELERATION OF THE AIR FLOW FOR WIND TURBINES

Device for accelerating the inlet air flow to a wind turbine (11, 21, 31, 41, 51, 61), comprising a diffuser (12, 22, 32, 42, 52, 62) configured to house a wind turbine (11, 21, 31, 41, 51, 61) substantially at the entrance of said diffuser (12, 22, 32, 42, 52, 62) in the direction of air flow. The outer (13, 23, 33, 43, 53, 63) and inner (14, 24, 34, 44, 54, 64) surfaces of said diffuser (12, 22, 32, 42, 52, 62) have a plurality of slits (15, 25, 35, 45, 55, 65) configured to transform the laminar boundary layer generated respectively in each of said turbulent boundary layer surfaces.
