Aerodynamics of the revolved cylinders system in a cross turbulent stream

Abstract

In this paper the possibilities of using a system of revolved cylinders as part of a wind turbine are considered. Experimental device and measurement technique were described. The aerodynamic forces in the cross-flow of a cylinder and a system of two cylinders have been measured. A method for determining the optimal distance between the cylinders in their cross-flow has been developed. We experimentally determined the conditions under which the Magnus effect contributes to the largest increase of a lift force and, correspondingly, to the increase of the wind turbine efficiency
