The Kaplan turbine is actually an extended version of the Francis turbine. Kaplan turbines are now used to generate high-current electricity. The Kaplan turbine is an inward flow reaction turbine, which means that the working fluid changes pressure as it moves through the turbine and gives up its energy. Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water. The design combines features of radial and axial turbines. Now let's look at the Kaplan Turbine Working Principle. This turbine is a kind of axial flow reaction turbine. In this way, the working fluid, which is often water, changes the pressure and generates energy as it moves inside the turbine. Power is a combination of kinetic energy of water flow and hydrostatic head.
What is a Kaplan Turbine? Kaplan turbine is a butterfly water turbine with adjustable blades. The turbine automatically adjusts the propeller blades with wicket gates to achieve efficiency over a wide range of flow and water levels.
