ABSTRACT

Photo-luminescent paints can be used in a variety of heat transfer and fluid mechanics experiments. By measuring the light emitted by the paint, detailed temperature, pressure, or concentration measurements can be obtained. Pressure sensitive paint (PSP) is used to obtain detailed pressure and film cooling effectiveness distributions on a surface. Temperature sensitive paint (TSP) can be used to measure detailed surface temperature distributions. Similar to IR and liquid crystal techniques, TSP can be used to measure detailed heat transfer coefficient distributions in both steady state and transient tests. To demonstrate the use of these photo-luminescent paints, detailed descriptions of the experimental setups, data acquisition, and data analysis are provided.
