    • The present invention relates to a wind turbine nacelle having a front end at which rotor blades are arranged and a longitudinal extension. The wind flows from the front end along the longitudinal extension defining a wind direction. The nacelle comprises a first face, and a cooling device comprising a cooling area and extends from the first face of the nacelle. The nacelle has at least one side with at least one opening for venting of air comprised within the nacelle. The nacelle further comprises an obstruction situated before the openings in relation to the wind direction in order to create a turbulent airflow outside the openings so that the nacelle is vented by dragging air out of the opening.

    • The present invention relates to an aerofoil (10) and a method for construction of the aerofoil (10). The aerofoil (10) comprises an outer wall (20) and an inner wall (30), wherein the walls (20,30) are separated by a cooling channel (40), and a coolant fluid (60) is guidable through the cooling channel (40) during the operation of the aerofoil (10). The inner wall (30) is provided with a protrusion (70), which is profiled and arranged such that it extends from the inner wall (30) into the cooling channel (40). The protrusion (70) directs at least a part of the coolant fluid (60) to impinge the coolant fluid (60) on a first region (64) of the outer wall (20).

    • An electrode (18) having a dielectric coating (20) is patterned to provide axially spaced rows (22) of insulating material (20) on the external surface of the electrode with one or more gaps (26) in the insulating material of each row. The electrode is placed in a preformed hole (16) of a turbine bucket and an electrolyte (32) is provided for flow between the electrode and the walls of the hole. Upon application of an electrical current, portions of the material of the interior wall surface directly opposite the non-insulated portions of the electrode are dissolved, forming grooves (29). The insulated portions of the electrode leave axially spaced rows of projections (30) extending toward the axis of the hole. The gaps (26) in the rows (22) are axially misaligned. The projections (30) form turbulators in the cooling flow passages of the bucket, enhancing the heat transfer coefficient.
