Abstract

The article discusses the effect of model materials, thickness, and coatings on the temperature variation and the accuracy of pressure sensitive paint (PSP) measurements. Moreover, a novel high thermal-conductive PSP is proposed to reduce temperature variation during wind-tunnel testing. PSP and the primary layer of low thermal conductivities blocked the conduction of heat from the model surface into the interior and increased the temperature variation on the surface. A white primary layer is widely used in PSP measurements due to several advantages. These results, however, revealed that thick primary layers increase the temperature variation during the wind-tunnel tests. Therefore, a primary layer should be as thin as possible. The high thermal-conductive PSP samples were evaluated experimentally using a calibration system. The pressure sensitivities and luminescence intensities of the PSPs were examined in a pressure chamber, where the pressure was controlled from 5 to 200 kPa by dry air and a vacuum pump.
