    Abstract

    An approach to combine the actuator line technique with the improved Brooks, Pope, and Marcolini (IBPM) model for wind turbine noise calculation is presented. The IBPM needs Mach number, local angle of attack and blade position as an input. These can be calculated accurately with the actuator line technique for any kind of flow conditions. We investigated laminar/ turbulent inflow, as well as wind shear and yaw of the 2.3 MW NM80 wind turbine. The turbulent case shows higher noise levels than the laminar one. Yaw changes the directivity from a dipole characteristic to an oval shape, inclined by the yaw angle.
