| Abstract: | The Variation of reaction was studied in details with different side surface and curvilinear angle of the last stage in 30MW steam turbine, through the Euler method to solutemultstages turbine on S2 steam surface, the calculation method of 3--D in annular cascadeswith high order accuracy TVD schemes and modeling experiment. The influence of the different side surface, lean angle and meridional surface on reaction was discussed, and it wasdeclare how these differences influenced the reaction in the last stage of 30MW steam turbinewith tine D/l. |
