Low pressure exhaust hood is one of the important parts in steam turbines, since the aerodynamic loss of exhaust hoods is nearly the same level of the loss of stator and rotor blading in low pressure steam turbines and there seems to be not little room remained for the enhancement of steam turbine efficiency. This paper presents the result of exhaust hood CFD analyses using last stage exit velocity distributions measured in the real scale development steam turbine as the inlet boundary condition to improve the accuracy of the CFD analysis.
