WebGoldstein, S. (1929) On the Vortex Theory of Screw Propellers. Proceedings of the Royal Society of London. Series A, 123, 440-465. WebThe vortex theory of screw propellers is modified and applied to high-speed horizontal-axis wind turbines. The turbine blade can be replaced by a bound-vortex system, and when the energy loss per unit time is a minimum, the trailing vortices move backwards with a constant velocity and build a helical-vortex sheet. A velocity-potential function which …
