Thin film heat transfer gage construction and measurement details
Abstract
Thin-film heat transfer gage construction and measurement in a compression tube facility are discussed. A step-by-step outline for applying the gages on ceramic substrates is given. Stanton numbers versus Reynolds number based on downstream distance are shown for a thermal boundary layer developing on a flat plate in a zero pressure gradient at a freestream Mach number of 0.64. The experimental uncertainty of the Stanton number data based on a 20:1 confidence level is + or - 9.5%. The uncertainty on heat flux rate at the surface is + or - 8%.
