But the development of a commercially successful machine would take another decade. Kaplan struggled with cavitations problems, and in 1922 abandoned his research for health reasons. DIAGRAM. CONSTRUCTION DETAILS OF KAPLAN TURBINE: The Kaplan turbine is an axial 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.

Kaplan Turbine is a type of reaction turbine which works is to produce electrical energy and it is used for high discharge and low heads.

Schematic of a Kaplan turbine and its components (Reference: green-mechanic.com) Working Principle of the Kaplan Turbine With Diagram. This turbine is one sort of axial flow reaction turbines. In this way, the working fluid, which is often water, changes the pressure while moving within the turbine and produces energy.
