Abstract
In recent years, OPMS (Optical Pressure Measurement System) using PSP ( Pressure Sensitive Paint) has been developed for measuring pressure distributions on wind tunnel models. To apply the PSP to measurement of pressure distribution on a solid surface settled in the rarefied gas flows, we had examined the fundamental features, such as pressure sensitivity and luminescence intensity. In this study, PtTFPP/poly(TMSP) is selected as a PSP and applied to investigation of pressure distribution on a solid-surface impinging a rarefied gas jet by PSP.
