Boundary Element Method Simulation Of Tonal Noise From A Wind Turbine

Xi Engineering

Modelling the acoustic output of wind turbines presents extreme simulation challenge due to the geometry of rotors and towers requiring very large mesh size with large volumes of empty space between blades. In this paper, the structural-acoustic finite element models that were previously presented at the Munich COMSOL Conference in 2016 (Stuber and Marmo, 2016) will be compared to simulations using the new COMSOL Multiphysics 5.3a boundary element method.
