PRELIMINARY BLADE LOADS ANALYSIS AND PERFORMANCE OF AN URBAN SMALL POWER VERTICAL AXIS WIND TURBINE

Raluca Dora IONESCU, Ioan SZÁVA, Mircea IVĂNOIU

Abstract


In this paper are analyzed the performances and torque magnitudes for a small power Vertical Axis Wind Turbine (VAWT).Starting from the Darrieus rotor, and applying a simplified analytical model, are determined the characteristic parameters of the design. The aim of the study is to investigate the influence of the geometric parameters and of the aerodynamic profile on the turbine power curve and on the torque distribution along the height of the turbine. This article is presenting the first step in the optimization of a new VAWT design. The study concludes that the moment distribution along the rotor height can be improved by changing several parameters.
