RÉSUMÉ
The steady state heat transfer characteristics were measured in a stationary generic four passage serpentine model of a turbine blade internal cooling passage. Turbulators were used to enhance heat transfer with a pitch to height ratio of 8.5:1 and blockage ratio of 0.1. Heated copper elements were placed at certain locations throughout the model with the ability to apply a known heat flux on the copper and measure the thermal response in the passages with thermocouples embedded flush with the passage wall. Nusselt numbers were calculated and compared with the literature.
