An ideal steam turbine is considered an isentropic process, or constant entropy process, where the entropy of the steam entering the turbine is equal to the entropy of the steam leaving the turbine. However, no steam turbine is truly isentropic and typical isentropic efficiencies range from 20% to 9

A steam turbine is a machine that extracts heat energy from pressurized steam and uses it to perform mechanical work on a rotating output shaft. Its modern representation was invented by Charles Parsons in 1884. [1][2] The manufacture of modern steam turbines involves advanced metalworking, using te

The stator winding is indirectly cooled, and the heat flows through the slot wall and is transmitted from the winding insulation to the iron core. For generators with a medium length or more, the base is used as a stator ventilation duct, so that air not only passes through the air gap but also enters each section of the iron core through the outer circle of the iron core, so that the axial temperature is evenly distributed.
