“…The general solution for PSP response to a change of oxygen concentration can be obtained using the Laplace transform [4]. The special solutions for a step change and a sinusoidal change of oxygen have been used for PSP dynamical analysis by a number of researchers [15,54,55,57,58,68].…”

Abstract:The current paper describes the development of pressure-sensitive paint (PSP) technology as an advanced measurement technique for unsteady flow fields and short-duration wind tunnels. Newly developed paint formulations have step response times approaching 1 ms, making them suitable for a wide range of unsteady testing. Developments in binder technology are discussed, which have resulted in new binder formulations such as anodized aluminium, thin-layer chromatography plate, polymer/ceramic, and poly(TMSP) PSP. The current paper also details modeling work done to describe the gas diffusion properties within the paint binder and understand the limitations of the paint response characteristics. Various dynamic calibration techniques for PSP are discussed, along with summaries of typical response times. A review of unsteady and high-speed PSP applications is presented, including experiments with shock tubes, hypersonic tunnels, unsteady delta wing aerodynamics, fluidic oscillator flows, Hartmann tube oscillations, acoustics, and turbomachinery. Flowfields with fundamental frequencies as high as 21 kHz have been successfully measured with porous PSP formulations.

“…Another dynamic characteristic of PSP is the steady-state response to a sinusoidal pressure change, i.e., the frequency response. Pioneering works on the frequency response of PSP by Engler [18] and Carroll and co-workers [15,19,20] revealed many items of note, but unfortunately, the apparatus used in their experiment could not produce pressure fluctuations at enough frequencies to evoke the potential of fast-responding porous PSPs such as proved in the shock-tube studies cited above. We may theoretically estimate the frequency response of a PSP from its step response assuming that the PSP measurement system is linear and time invariant.…”

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.
