The Francis turbine was invented by the American inventor James B. Francis in the 1800s. The Francis turbine is an inward flow reaction turbine and is used in devices with a wide variety of head and flow.
The Francis Turbine is the most commonly used turbine today to generate hydroelectricity. They are often used in large hydroelectric dam systems.
The Francis turbine is a versatile turbine that can be built with either a horizontal or vertical axis and can be used in many different hydraulic head heights and water flow levels.
This turbine also uses mobile guide vanes to direct the water into the turbine which can be set to allow the desired level of water flow into the turbine system.
