Geometric and flow features considered in three-dimensional studies were a seal cavity between rotor and stator, seal cavity flow, fillet geometry, and inlet boundary layers with and without seal cavity. Despite differences in blade external heat transfer of 10% - 15% in the life-limiting region, the estimated life for all blades in these studies was within 2.6% of the nominal. For turbine blades of similar design and operating conditions, given our modeling approach, it was concluded that (1) the level of heat transfer differences observed between blade designs does not play an important role in the estimation of blade life and (2) high fidelity modeling of external aer.
