Examples
A turbine composed of moving nozzles alternating with fixed nozzles is called a reaction turbine or Parsons turbine.
Whilst this makes the Parsons turbine much longer and heavier, the overall efficiency of a reaction turbine is slightly higher than the equivalent impulse turbine for the same thermal energy conversion.
A reaction turbine needs to fully contain the water during energy transfer.
The Francis reaction turbine is still in wide use today.
