AB - The present paper presents the aeroacoustic calculation methodology for the  H-Darrieus wind turbine. The CFD analysis, for different wind turbine  blades' angles of attack, coupled with the noise analysis, based on  Lighthill and Prudmann models is performed. This type of turbine is of  particular interest since it is insensitive to wind direction and can be  used in urban areas. In this study commercial software, ANSYS is used for  CFD and aeroacoustic analysis. The required turbulent flow field is  calculated based on the standard k-ε model, and reequired model constants  are obtained experimentally in a low-Mach number wind tunnel. The noise  levels generated by operating turbine are calculated based on Lighthill and  Proudman's aeroacoustic theories. It was found that the methodology  presented can be efficiently used in noise analysis of vertical axes wind  turbines and due to recent strict noise regulations has to be deployed at  the early design stages.
