Abstract

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 130 Pa (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 NO-LIF 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.
