Types Of Water Turbines - Waterturbines

There are two main categories of hydro turbines: impulse and reaction,as described above. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water, at the site. The most common type of impulse turbine is Pelton turbine.There are also Turgo turbine, Cross-flow turbine (also known as the Bánki-Michell turbine, or Ossberger turbine),Jonval turbine,Reverse overshot water-wheel,Screw turbine.On the other side,the most common reaction turbine is Francis turbine but there are also Kaplan turbine,Tyson turbine,Gorlov helical turbine.
