Cross-flow (Banki-Michell) turbine

A water turbine with a horizontal shaft in which water flows through the runner and hits the blades twice, suitable for small water power plants. A cross-flow turbine has a relatively cheap and simple design, and its performance does not change significantly with changes in flow. It has the shape of a horizontal cylinder fitted with numerous blades, arranged radially and tangentially. The water directed by the nozzle hits the top of the turbine, is reflected into the turbine, and hits the blades again as it exits at the bottom of the turbine.
