Flow and Thermal Measurements in Film Cooling Flows

Mission Statement:
In supporting the current needs and
state-of-the-art in the gas turbine community, the fundamental goal of
this research program is to provide detailed experimental
documentation of flow and heat transfer phenomena in film cooling
flows. To date, detailed documentation of mean flow fields, local
turbulence distributions, transport quantities, and surface heat
transfer in an "engine-representative" film-cooling environment has
eluded researchers. Many of these items have been provided through
this research program via experimental measurements with hot-wire
anemometry and thermocouple techniques. In addition, sensitivities of
film cooling flows to the hole and supply plenum geometries have also
been an unsettled issue. Further experimental documentation of the
effects of hole and supply plenum geometry on film cooling performance
has also been provided. The documentation provided is critical to the
basic understanding of mainflow-coolant interactions and for
supporting accurate computational models.
