Abstract
The article presents the results of modeling air flow in a turbulent mode of flow around a wind device as profiles and fields of pressure and velocity. The simulation was performed with the help of the COMSOL software package. The axial velocity profile, pressure coefficient around the blade and instantaneous power coefficient of one blade using the transient SST model are in good agreement with the experimental data. The presented values of the device’s power factor Cp were obtained using different turbulence models. When mathematically modeling the flow around a vertical axis wind turbine, the transient SST turbulence model can be used, which provides satisfactory results.
