Francis Turbine is a reaction turbine, which was developed by English born American Engineer Sir J. B. Francis. The water enters the turbine through the outer periphery of the runner in the radial direction and leaves the runner in axial direction and hence it is called a mixed flow turbine. As the water flows to the runner, a part of pressure energy goes on changing into kinetic energy. Thus the water through the runner is under pressure. The runner is completely enclosed in a air tight casing and the casing & runner is always full of water. The main aim is to effectively understand the performance characteristics of a Francis Turbine Test Rig. The other objective is to effectively understand the construction and operation of a Francis Turbine. The turbine will be powered by a centrifugal pump, which will be driven electrically. The
turbine output will be measured by a dynamometer. A water tank, piping, and other required accessories must be supplied with the test rig. Self-explanatory operating manuals will be provided with each system. Detailed theory, as well as practical exercises, will be included in the manual.
