A comparison of modelling wind turbine noise using FEA and BEM approaches

Xi Engineering

Broadband and tonal noise produced by wind turbines can have detrimental effects on neighboring residential communities. Xi Engineering Consultants have previously used COMSOL Multiphysics to design and optimize mitigation solutions targeted at the tonal component of wind turbine noise . To overcome the necessity of modelling the void spaces between blades, a novel approach was used whereby the acoustic fields around the blades and towers are modelled allowing the modelling of large turbines (up to 100 m) and higher frequencies (up to 200 Hz).
