Short summary
With the rapid advancement of computer science and technology, the use of CFD technology has become increasingly prevalent as a formidable means of exploring the aerodynamics and aeroacoustics of wind turbines. The acoustic power and moment of a 5 kW vertical-axis wind turbine (VAWT) were simulated by using different mesh sizes and turbulence models. This paper provides valuable information on simulating noise propagation from small VAWTs and the optimal noise reduction techniques.
