Abstract
A performance optimization based on Computational Fluid Dynamics (CFD) for exhaust hoods of low pressure steam turbine wasconducted A low pressure exhaust hood must be designed promptly m a design process of a steam turbine plant In order to design a low pressure exhaust hood for longer rotor blades rapidly, a database based on conventional CFD analysis results was applied By using this database, the number of CFD analysis for performance designs of low pressure exhaust hoods was reduced Further, validations of these designs were conducted using air test apparatus From these results, the effectiveness of this performance optimization process was confirmed
