“…For these reasons, H 2 TFPP was used in the present experiment. This optical probe was originally developed for the detection of chemiluminescence from radical species in an extremely small volume of flames [25], and can effectively collect the light emitted from the area within 0.1 mm in diameter [26].…”

Optical measurements of high-frequency pressure fluctuations have been performed to examine the dynamic response of a fast-responding porous pressure-sensitive paint (PSP). The PSP was composed of meso-tetra(pentafluorophenyl) porphine and a commercial silica-gel thin-layer chromatography plate. Pressure fluctuations at frequencies on the order of kilohertz were produced on a flat plate by chopping an underexpanded air-jet and then measured by using a newly developed, optical pressure measurement system (OPMS) with a Cassegrain-type optical probe. Pressure traces obtained by the present OPMS and their amplitude spectra were compared with those obtained by a piezo-resistive pressure transducer. The present results demonstrate the feasibility of the present OPMS for measuring high-frequency pressure fluctuations with a high spatial resolution and reveal that the present porous PSP can follow pressure fluctuations at frequencies of several kilohertz at least.

The aim of the present work is to demonstrate the feasibility of a porous pressure-sensitive paint (PSP) for time-resolved surface pressure measurements in unsteady flows. The porous PSP was composed of bathophenantholine ruthenium(II) complex, Ru(Phn-phen), and a silica-gel thin-layer chromatography (TLC) aluminum plate. The dynamic response of the porous PSP was characterized by applying it to rapid pressure changes generated by a shock wave and a pulse-jet. The porous PSP was then applied to the transient starting process of flow in a twodimensional Laval nozzle with a fast-framing complementary metal oxide semiconductor (CMOS) camera. It has been shown that the present imaging system can well capture a rapid flow evolution on the order of kilohertz such as shock wave motion in the nozzle during its starting process.
