Treating temperature-sensitivity effects of pressure-sensitive paint measurements

Characterization of pressure dynamics in an axisymmetric separating/reattaching flow using fast-responding pressure-sensitive paint

“…The worldwide application of PSP to assess fluidmechanical problems in wind tunnels at larger research facilities like NASA, DLR, JAXA, ONERA dates back to the mid-1990s. As reported by Airaghi (2006), Crafton et al (1999), Nakakita (2007), Woodmansee and Dutton (1998), Yang et al (2012), this technique is increasingly used at university departments. The Institute of Fluid Mechanics and Aerodynamics began its installation of a PSP-system several years ago, see Bitter et al (2009).…”

Red‐ and Green‐Emitting Iridium(III) Complexes for a Dual Barometric and Temperature‐Sensitive Paint

“…TSPs use gas-blocking matrix polymers in order to avoid the quenching of luminescence by oxygen. [11,12] The relationship between polyAbstract: A new dual luminescent sensitive paint for barometric pressure and temperature (T) is presented. The green-emitting iridiumA C H T U N G T R E N N U N G (III) complex [IrA C H T U N G T R E N N U N G (ppy) 2 A C H T U N G T R E N N U N G (carbac)] (ppy = 2-phenylpyridine; carbac = 1-(9H-carbazol-9-yl)-5,5-dimethylhexane-2,4-dione) was applied as a novel probe for T along with the red-emitting complex [IrA C H T U N G T R E N N U N G (btpy) 3 ], (btpy = 2-(benzo[b]thiophene-2-yl)pyridine) which functions as a barometric (in fact oxygen-sensitive) probe.…”

Ideality of pressure-sensitive paint. II. Effect of annealing on the temperature dependence of the luminescence

“…The pressure-sensitive paints are much more affordable and, with charge coupled device (CCD) camera sensors, produce a virtually continuous pressure map. However, major problems limit the use of these paints in aerodynamical studies: correction for the model movements during analysis, 6,7 slow response time of many paints, 8,9 temperature dependence of the luminescence, 10,11 and self-illumination. 12,13 In this article, we explore one feature of practical value for the use of PSP: the role of annealing the paint in achieving ideal PSP properties.…”

“…24 A good comparison of different temperature correction methods was published by Woodmansee and Dutton. 11 However, the possibility of effective and useful temperature correction of PSP is limited by the nonideal behavior of most of the PSP available.…”
