Transient Flat Plate
Flat plate experiments provide a way to explore challenging concepts in a simpler environment than the full turbine. At the GTL, they are commonly used to explore new experimental or data processing techniques as well as for comparison to computational predictions. Codes that are not able to predict heat transfer to a flat plate will have a difficult time making predictions for an operating turbine.
Recent experimental and computational programs have examined the influence of film cooling for a hole pattern representative of the pressure surface of a high-pressure turbine blade. In addition for providing new insight into the interactions among multiple rows of cooling holes, this experiment also helped validate a new method of injecting cooling streams into a transient facility that has since been applied in the TTF.
