Description

The De Laval turbine used trumpet shaped nozzles to extract most of the expansion energy from the steam. It is the use of multiple stages and more gradual steam expansion among the stages that leads to the greater efficiency at slower speeds. The different diameters at each stage are what allow for expansion on steam turbine rotor.
