Two in-house Pressure-Sensitive Paint (PSP) formulations have been developed and tested in the low-speed regime on the flow around a U-bend of strong curvature. The two PSP formulations use trisBathophenanthroline Ruthenium Perchlorate (Ru (II)) and Platinum tretakis (pentafluorophenyl) Porphyrin (PtTFPP) as their photoactive molecules, incorporated in identical sol-gel matrices. Ru (II) emits a broad peak centered at 610nm while PtTFPP emits a much narrower peak at 650nm. The paints were illuminated using two in-house constructed blue LED lights with peak emission of 468nm. These luminophores have been tested with gauge inlet pressures of 3000 and 1250 Pa respectively. A further sample was tested with a gauge pressure of 500 Pa. In-situ calibration was utilized to minimize the temperature dependency change between wind-on and wind-off images. Both paints captured the flow characteristics and gave predictable surface pressure maps despite the challenges inherent with using such low pressures.

Of these researchers Bell [3] and Le Sant [7] managed extremely low errors (± 50 Pa). However, all of the applications of PSP to low-speed flow have been performed in large-scale wind tunnels. To this end it was decided to test the PSP formulations in use at the University of Manchester on a low-speed, internal flow.

“…Eu 3+ -doped phosphors exhibit high-intensity emission lines in the spectral red region. These red phosphors have been used as a reference luminophore in surface pressure sensor coatings for aerodynamic applications (popularly known as pressure sensitive paints, PSPs) to apply correction for excitation intensity variations during wind tunnel tests [7][8][9][10][11][12]. The main advantage of PSP technique compared to pressure transducers is the high spatial resolution of surface pressure data on the model surface.…”

“…Eu-doped gadolinium oxysulphide has been used as reference dye in pyrene-based binary PSPs [7,8]. Basu et al [9] have used Eu-doped rare earth oxysulphide as reference luminophore for a novel pyrene-based binary PSP with improved stability.…”

“…The problem is more difficult at low speed because of the smaller variations in pressure. Figure 11 shows an investigation carried out at ON-ERA [29]. The PSP is made of pyrene with gadolinium oxysulfide as reference dye (insensitive to oxygen), which permits correction for the nonhomogeneous distribution of illumination.…”
