Description
Miral Michel and co-authors present a 2026 engineering article on gravitational water vortex turbines. These small turbines draw power from slow rivers and channels where the water drops only a short distance. Water swirls into a cone-shaped basin and spins a rotor as it drains.
Using a three-dimensional computer model of water flow, checked against published data, the team varied blade shape, blade size, and spacing. Basin walls shaped like airfoils, the curved profiles used on wings, steered the flow and boosted the spin passed to the rotor. One ducted blade design scored far above the plain basin at its best settings. The authors argue that shaping the basin matters as much as shaping the turbine itself for low-head sites.
