Francis turbine - Wikipedia
The Francis turbine is a type of water turbine. 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, and can achieve over 95% efficiency.

Francis Turbine: Definition, Working, Components, Efficiency, and ...
Francis turbine is a mixed flow turbine. In a Francis turbine, the water enters radially to the runner blades while exits axially. It is a combination of a reaction turbine and an impulse turbine. Francis turbines are most commonly used in large or medium hydropower plants to produce electricity.
Francis Hydro Turbine - GE Vernova
With about 60% of the global hydropower capacity in the world, Francis turbines are the most widely used type of hydro turbine. GE has continuously invested in R&D to increase turbine efficiency and developed specific product enhancements to improve machine performance.
Types of Hydropower Turbines - Department of Energy
Francis Turbine: The Francis turbine was the first modern hydropower turbine and was invented by British-American engineer James Francis in 1849. A Francis turbine has a runner with fixed blades, usually nine or more. Water is introduced just above the runner and all around it which then falls through, causing the blades to spin.
Francis Turbines - an overview | ScienceDirect Topics
The Francis turbine is a mixed flow-type turbine in which the water passes through the curved guide vanes and creates a high curved rotational flow at the outlet. A draft tube is connected at the end of the turbine, and this draft tube aids to improve the overall efficiency of the reaction turbine by pacifying the excess kinetic energy of the ...
Francis Turbine – its Components, Working and Application
An American civil engineer by name, James B. Francis in Lowell, Massachusetts comes up with an idea of combining both impulse and reaction turbine where water enters the turbine radically and exits axially. The working principle, main components …
Francis turbine - Energy Education
A Francis turbine is a type of reaction turbine used most frequently in medium- or large-scale hydroelectric plants. These turbines can be used for heads as low as 2 meters and as high as 300 meters. Additionally, these turbines are beneficial as they work equally well when positioned horizontally as they do when they are oriented vertically.
Francis Turbine - Renewable Energy Sources - Energy Encyclopedia
Francis turbines designed for generating electricity with an efficiency exceeding 90% are suitable for heads between 20 and 700 meters and their output ranges from a few kW to 1,000 MW. The runners of Francis turbines installed in the biggest hydroelectric power plants in the world can have a diameter of more than 10 meters.
Francis Turbine – Diagram, Working, Parts , Advantages, …
The Francis turbine is a type of reaction turbine that was developed by James B. Francis. Francis turbines are the most common water turbine in use today. They operate in a water head from 40 to 600 m and are primarily used for electrical power production.
