Temperature Measurement Using Fluorescent Molecules,

Abstract

The temperature dependence of the fluorescence of several compounds in various polymer bases has been calibrated. These fluorescent 'paints' are applied to a wing section and a delta wing model to determine the temperature distributions on the surface in an air flow. The time history of the temperature distribution can then be used to determine heat transfer rates. The difference in convective heat transfer between laminar and turbulent flow allows the visualization of boundary layer transition. (Author)
