抜粋

The causes of disagreement between a priori and in situ results of Pressure-Sensitive Paint (PSP) measurements in cryogenic wind tunnels have been investigated. Systematic experiments were conducted in the JAXA 0.1-m cryogenic wind tunnel to clarify the factors of the disagreement. In the experiments, the influence of total and static temperatures, and oxygen concentrations in the cryogenic wind tunnel on PSP results were evaluated. Consequently, it was detected that this disagreement originates in the difference between a total pressure-change calibration and a partial oxygen pressure-change calibration, and the hysteresis of luminescent intensity during pressurization and depressurization process at low temperatures less than 110 K.
