MODELING AERODYNAMIC CHARACTERISTICS OF A WIND ENERGY INSTALLATION WITH ROTATING CYLINDER BLADES ON THE BASIS OF THE ANSYS SUITE

Modeling has been carried out for the aerodynamics of air fl ow past the windwheel with three cylinder blades rotating around their axis using the Ansys suite. A system of equations in approximation of a realizable k–ε turbulence model was solved by the method of fi nite volumes using the approach of multiple (imbeddable) systems of coordinates. Patterns have been constructed for vortex zones near cylinder blades. Analysis is given of the aerodynamic characteristics of fl ow past rotating cylinders under the conditions of the operation of a wind turbine using the Magnus eff ect depending on the velocity of cylinders′ rotation and the Reynolds number. Dependences have been obtained for the drag force of the windwheel, the lift force of the cylinder, and also the force moment on the velocity of approach fl ow
