Abstract
The article discusses the results of numerical simulation of the flow around a wind wheel with blades in the form of rotating cylinders using the software package ANSYS. The advantage of a wind turbine with rotating cylindrical blades in comparison with traditional blade installations is the starting moment and the beginning of energy production at a wind speed of (2 - 3) m/s. A mathematical model has been developed based on threedimensional Navier-Stokes equations in a rotating system. The corresponding boundary conditions are formulated. A calculated pattern of the flow around the wind wheel with rotating cylindrical blade is obtained. There are shown regions of the velocity field with turbulent vortices, which are formed at high Reynolds numbers. The degree of influence of the angular speed of rotation of the wind wheel on the magnitude of the moment of forces at various speeds of the incoming air flow has been determined.
