Wet Vapor Turbine Flow Study

DAVID H. EVANS, WALTER D. POUCHOT, GERALD J, BARNA

Abstract

With the increasing application of central station nuclear power plants and the higher moisture levels in the steam turbines, there has been likewise a high level of interest in these phenomenon by Westinghouse Electric Corporation. The work described in this paper was performed by Westinghouse under NASA contract.

This experimental program was aimed at improving our understanding of the moisture flow in wet-vapor turbines. A multistage steam turbine was used as thę test vehicle, Objectives of the program were threefold: (1) visualization of the moisture flow in the turbine through high speed photography and visual observations; (2) measurement of the effectiveness of rotor casing slot and stator trailing edge slot moisture removal devices; and (3) measurement of the effects of the moisture on turbine effciency.

Keywords:

nuclear power plants, moisture levels, steam turbines, effectiveness of rotor casing slot, turbine effciency.
