Pressure and Temperature sensitive paint
Pressure sensitive paints (PSP) were developed to provide an optical technique that enables global pressure measurement over an entire model. PSPs work by using a dye that fluoresces when exposed to light of a certain wavelength. The intensity of fluorescence can be quenched by oxygen in the flow field. From the change in luminescence intensity, a linear calibration can be obtained and used to determine the pressure on the model surface. Temperature sensitive paints (TSP) work in a similar fashion, however, the luminescence is quenched thermally.
Current research involves investigating alternative methods to increase luminescence output by developing novel dye molecules, highly-tailored dye molecules, amendments to add to current PSP formulations, and alternative binders. Highly-tailored dye molecules and the addition of amendments offer numerous unique advantages such as being able to use traditional dye molecules that are well understood, exhibit high stability, and behave well under PSP testing.
