The Francis turbine is a type of water turbine that was developed by James B. Francis in Lowell, Massachusetts. It is an inward-flow reaction turbine that combines radial and axial flow concepts.. Francis turbines are the most common water turbine in use today. They operate in a water head from 40 to 600 m (130 to 2,000 ft) and are used primarily for electrical power production Francisturbin er den mest brukte turbintypen i norske vannkraftverk. Turbinen ble utviklet av den engelske ingeniøren James B. Francis i 1849. Denne turbintypen er best egnet ved middelsstore og store fallhøyder (mellom ca. 30 og 600 m). Er fallhøyden lavere benyttes ofte kaplanturbinen, er fallhøyden høyere benyttes peltonturbinen.. Francisturbin er en vannturbin for lavere og midlere fallhøyder; fra 50-750 meter. Det er den mest brukte turbintypen i norske vannkraftverk.Etter å ha passert stillbare ledeskovler ledes vannet radialt inn på løpehjulet. Gjennom løpehjulet avbøyes vannstrømmen til aksial retning, og forlater turbinen gjennom sugerøret ned til undervannet (avløpet), slik at hele fallhøyden blir.
