Abstract: Cooling flow behavior is investigated within the multiple serpentine passages with turbulators on the leading and trailing walls of an axial gas turbine blade operating at design-corrected conditions with accurate external ...

Abstract: Predicting cooling flow migration and its impact on surface heat flux for a turbine operating at designcorrected conditions is a challenging task. While recent data sets have provided a baseline for comparison, they have ...

Abstract: The flow field in axial gas turbines is driven by strong unsteady interactions between stationary and moving components. While timeaveraged measurements can highlight many important flow features, developing a deeper ...

Abstract: Measurements are presented for a high-pressure transonic turbine stage operating at design-corrected conditions with forward and aft purge flow and blade film cooling in a short-duration blowdown facility. Four different ...
