Keywords: turbine, cfd,aerodynamic forcing

The effect of the parametric variation of stator blade geometry on stage aerodynamics. The adopted criterion for comparison is the generalized force obtained by the projection of the unsteady aerodynamic forces onto the rotor blade natural mode shapes derived by means of a finite element analysis.
