Reaction Turbines
Reaction turbines work a little differently than impulse turbines. Rather than each blade being struck individually, the turbine is rotated by the flow of water over all of the blades. Generally, these turbines are more useful in areas with low head and high flow such as in run of the river plants and tidal stream generators.
Propeller
The runner on propeller turbines have three to six blades, all of which are constantly in contact with the water. Pressure is constant in the pipe to maintain balance. The angle of the blades can be varied depending on the need. There are a number of propeller turbines to choose from.-
