SAVONIUS WIND TURBINE RATIOS

Solicitante:

FARB MARK DANIEL [IL]

CN_112912621_A

Resumen de: WO2020100133A1

A Savonius wind turbine has been noted in the past to have the capability to perform more efficiently than other drag-type vertical axis turbines when built according to certain parameters. The previous literature has missed seeing the ratio of the shaft diameter to the available space for wind to pass through in the center as the crucial relationship on which other improvements in this type of turbine can be built. The chord diameter and overlap distance all depend on the size of the central shaft and its ratio to the inner endpoints of the overlapping semicircular blades. The ratios for maximal efficiency are presented here. These efficient ratios also depend for their execution on the turbine rotating at an ideal tip speed ratio.
