The pressure sensitive paint (PSP) technique has the capability to be applied to high Knudsen number flows, such as low density gas flows, micro-flows, and so on. In this study, to inspect the feasibility of PSP for measurement of pressure on a solid surface in the high Knudsen number flows, fundamental properties of three types of PSP [PdTFPP, PdOEP and PtTFPP bound by poly (TMSP)] are examined especially in the range of pressure below 130Pa (about 1 Torr). The pressure sensitivity against nitrogen monoxide is also examined for the above PSPs, to develop a technique for the composite measurement of the flow field structure and the surface pressure, using NOLIF and PSP, respectively. As an application of PSP to low density gas flows, we measure the pressure distribution on a jet-impinging solid surface using PdOEP/poly (TMSP) with very high pressure sensitivity.
