An experimental investigation of the heat transfer to a turbine vane at simulated engine conditions
Abstract
Full application of 2D boundary layer calculations for heat transfer predictions during turbine vane design still awaits verification against relevant data. Although there are a few data sets in the literature, there is a definite need for basic vane heat transfer data under conditions that fully simulate the aerodynamic and thermal conditions of a modern turbine. Accordingly, an experiment was performed to obtain the local heat transfer distribution on a typical engine vane in an aerothermodynamic cascade facility. Heat transfer data were obtained for a range of Mach and Reynolds numbers. The cascade was closely coupled behind the facility burner so that the test included the effects of high free-stream turbulence. Turbulence data were obtained by LDV and are included.
