Abstract
The present paper describes the temperature dependence of the pressure sensitive paints in the pressure range of 1101.3kPa, and the wall temperature range of 263303K. The pressure sensitive paints investigated in the present work are PtOEP, PtTFPP, H2TFPP, H2TCPP, H2TSPP, and H2TTMAPP, and painted on a commercial porous silica thin-layer chromatography (TLC) plate. We estimate the uncertainty of the measured pressure value due to the change in the wall temperature. As a result, the uncertainty of H2TFPP is smaller than 3.5kPa per Kelvin in the present measuring range, and this paint is the most useful paint among the PSPs tested in the present work for measuring the surface pressure of the aerodynamic body on which there are temperature distributions.
