“…A scramjet inlet model coated with AA-PSP was tested in a Mach 4 short duration Ludwieg tube by Sakaue et al 11 The surface pressure was in the order of hundreds of Pascals and the test duration was around 100 ms. The AA-PSP captured the surface pressure change well and the results agreed with the CFD findings.…”

Depending on the case study examined, different PSPs may be used, each applied using a different method onto the model. For polymer PSP the paint is sprayed on. In contrast, the model may first be anodized or covered with a thin-layer chromatography plate and then dipped in PSP. The objective of the present study is to analyse the characteristics of different PSP substrates at high Mach numbers which use two well known PSP molecules: (i) tris-Bathophenanthroline Ruthenium (II) Perchlorate and (ii) Platinum-tetrakis (pentafluorophenyl) Porphyrin. Using a double ramp geometry under a Mach 5 hypersonic flow the feasibility of applying each of the aforementioned PSP methods is investigated and compared to discrete pressure measurements. The flow over a 3D bump under a Mach 1.3 flow is also studied to give a broader Mach number range. In the hypersonic tunnel, all PSP techniques and formulations were able to capture the complex flowfield with the results quantitatively agreeing with the discrete measurements. For the transonic bumps however, it was found that the polymer based Platinum PSP could map the flowfield more accurately.

“…To increase the emission signal level, a base coat is usually added on the model surface underneath the PSP layer. The polymer based PSP has been successfully applied in low speed, 5,6 transonic, 7-10 supersonic, [11][12][13][14] and hypersonic flows.…”

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.

“…It is found that the temperature 13 effect is less than 4% except the model nose and shock impingement region. In a shock tunnel test by Sakaue et al 27 , pressure measured from the uncorrected AA-PSP on hemisphere and scramjet inlet model shows pressure uncertainties of 4-6 percent with comparison with CFD results in shock tunnel test. 26 Gregory et al 26 concluded that several Kelvin of surface temperature rise in the shock tunnel test is almost negligible for thin PSP coating because of the small heat mass.…”
