Title: The design and characterization of a prototype optical heat-flux gauge

Technical Report ·
OSTI ID:6546396

We have demonstrated the feasibility of using thermographic phosphors as the temperature sensors in an optical surface-heat-flux gauge. A heat flux of 40 kW/m/sup 2/ was measured with a gauge constructed by depositing La/sub 2/O/sub 2/S:Eu and Gd/sub 2/O/sub 2/S:Tb phosphors on the two faces of a polymethylpentene insulator. In the experiment, we measured a steady-state heat flux at a single point on a stationary surface; however, the gauge is also intended to measure transient heat flow. The technique is conceptually expandable to a two-dimensional temperature measurement. 17 refs., 10 figs., 1 tab.
