“…A total of six samples were placed in the calibration chamber: the PtTFPP-polymer, PtTFPP-AA-PSP, and PtTFPP-TLC, Ru(dpp) 3 -polymer, Ru(dpp) 3 -AA-PSP, and Ru(dpp) 3 -TLC. According to the findings of Quinn et al 18 the polymer based paints gave the strongest signal followed by the TLC plate. The AA-PSP signal was the lowest.…”

“…18 Generally, the thin-layer chromatography (TLC) and anodized aluminium seem to be the most frequently used porous binder for PSP applications in high speed flows. The micropores on the porous binder absorb the luminophore molecules via the internal-molecule force.…”

“…All the static samples (no flow) were simultaneously tested in a sealed calibration chamber by Quinn et al 18 where pressure and temperature can be controlled; some of their findings are presented here for completeness. A total of six samples were placed in the calibration chamber: the PtTFPP-polymer, PtTFPP-AA-PSP, and PtTFPP-TLC, Ru(dpp) 3 -polymer, Ru(dpp) 3 -AA-PSP, and Ru(dpp) 3 -TLC.…”

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.

“…The temperature sensitivity of the current AA-PSP formulation is found to be approximately -0.64% per degree. 39 The temperature rise during the test duration will cause considerable error if it is uncorrected. However, in the current setup in-situ calibration was applied to convert the AA-PSP images to pressure maps.…”

“…The temperature sensitivity of the present AA-PSP substrate has been measured by Quinn et al 46 and a -0.64%/ dimensional compression/expansion ramp and three dimensional wing-body model. 33,34 The standard deviation of the uncorrected AA-PSP measurement and the Kulite transducer reading on twodimensional model is about 2.6%.…”
