Introduction of Inclined-jet turbine
Inclined-jet turbine: The pressure energy of water flow is changed to velocity energy by the nozzle, since leaving the nozzle, the water flow is not in a closed system, but forms the free jet in the spiral casing filled with atmosphere, and at the same time there are 3-4 buckets receiving the free jet from the same nozzle with unequal-sized discharge. There was a fixed angle (usually take 22.5 degree) between the jet center of nozzle exit and the inlet water plane of runner.
