Abstract

See full text

A vertical axis turbine includes a vertical rotary shaft and turbine blades mechanically coupled to the vertical rotary shaft, each of the turbine blades including curved rounded physical geometries on a leading edge. A method of reducing drag includes improving lift over an air foil design using curved rounded physical geometries on a leading edge of hydrokinetic vertical axis blades that produce channels of high and low pressure water flows over a surface of the hydrokinetic vertical axis blades.
