Energy Efficiency Assessment of Four Designs of Vertical Axis And Drag Differential Wind Turbines
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 1
Abstract
The present study compares the energy efficiency of four different wind turbine designs with vertical axis and differential drag, keeping equal their heights and diameters. Besides the classic two bladed Savonius model, two models derived from it were studied (Schulz and Beneshi), as well as the barely known Lenz type turbine. In laboratory tests of scale models the power curves have been determined as a function of the tip speed ratio, exposing the turbines to wind velocities up to 7 m/s. To avoid any variation in friction between tests, the same base, alternator and gears have been used for all four models. The Lenz model outperformed all others having the best power coefficient.
