Research of aerodynamic characteristics of the wind generator on the basis of Magnus's effect

Abstract

The paper presents the results of experimental tests of a wind generator with elements in the form of rotating cylinders. The results of studies of the traction force on the speed of air flow in the direct and opposite direction of the wind flow are presented. Also results of research of factor of force of draft of a wind generator with blades by a porous surface from Reynolds number at direct and opposite directions of a stream of a wind are resulted. It is shown that the tractive force coefficient retains an operative value of up to 450, then, with increasing angle, the skew of the wind flow slowly decreases. It is established that the prototype of the wind power plant works effectively when the angle of the bevel of the direct wind flow varies within the range of – 45⁰ ÷ + 45⁰. This work has great relevance in the development of wind turbines for low wind speeds based on the Magnus effect. The authors show the results of the dependence of the traction force of the wind turbine with the blades in the form of rotating porous cylinders on the flow velocity in the forward direction of the wind, i.e. Towards the front of the wind wheel. It is established that at a constant wind speed, the value of the tractive force coefficient decreases with an increase in the bevel angle, which is explained by a decrease in the area of the meander section of the wind wheel.
