| Abstract: | The aerothermodynamic performances of high and intermediate pressure cylinders of 200MW steam turbine under operating condition have been analyzed with quasi-three dimensional method. Mach number distribution on profiles and the shortcoming of the old profiles are analyzed by S1 calculations. Radial distribution of aerothermodynamic parajmeters are obtained by S2 calculations. Some important parameters including enthalpy drop, incidence angle and loss distribution are analyzed. Finallyl some proposals are put forward for redesign. |
