The steam flow past a last stage (the eleventh stage) of the high pressure part of the TK120 steam turbine was investigated using computational fluid dynamics (CFD). The simulations are performed using the unsteady compressible Navier-Stokes equations. Viscous steam flow has been analyzed using the Spalart-Allmaras turbulence model. The paper presents distributions of instantaneous flow parameters around turbine blades as well as instantaneous aerodynamic blade loads. Flow parameters such as: velocity and static pressure are presented as contour maps whereas aerodynamic loads, axial and circumferential, are given as functions of time. Theoretical power of the examined turbine stage is 4.11 MW. Based on the numerical investigations the power of the analyzed stage is evaluated to be 3.5 MW. All presented in this paper results have been performed using the ANSYS Fluent solver.
