摘要：
A three-dimensional numerical analysis for aerodynamic unsteady forces and fitter parameters of the last stage steam turbine 13K215 rotor blades have been presented. The low frequency excitation was simulated for a 94 rotating blades with 54 nozzles. It was assumed that the pressure behind the rotor blades is changing in the circumferential direction. The flutter parameters of this stage were calculated.
