Investigation of the Optimum Clocking Position in a Two-Stage Axial Turbine
A frozen rotor approach in a steady calculation and a sliding mesh approach in an unsteady simulation are performed in a stator clocking investigation. The clocking is executed on the second stator in a two-stage axial turbine over several circumferential positions. Flow field distributions as well...

| description | A frozen rotor approach in a steady
calculation and a sliding mesh approach in an unsteady simulation
are performed in a stator clocking investigation. The clocking is
executed on the second stator in a two-stage axial turbine over
several circumferential positions. Flow field distributions as
well as the estimated performances from two approaches are
compared with each other. The optimum clocking positions are
predicted based on the estimated efficiency from the two
approaches. The consistence of the optimum clocking positions is
discussed in the paper. The availability and the limit of the
frozen rotor approach in predicting the optimum clocking position
is analyzed. It is concluded that the frozen rotor approach is
available to search the optimum clocking position in the
preliminary design period, although it misses some features of the
unsteady flow field in the multistage turbines. |
