Measurements and applications of fast response pressure sensitive paint

The fast response pressure sensitive paint measurement technique has been developed quickly in recent years. A general review of this technique based on detailed investigation is presented. The characteristic, principle and dynamic response mechanism are described. Three kinds of porous structure fast response pressure sensitive paint are introduced, including TLC-PSP, AA-PSP and PC-PSP. Several dynamic calibration devices are introduced, including the shock wave tube, fast response solenoid valve, loudspeaker, jet oscillator and pulse jet. Different measurement methods are introduced including the point measurement, phase averaging, high speed acquiring, motion-capture measurement, life time method, and PSP microspheres method. Different application cases around the world are introduced, which manifests the advantages of the fast response PSP technique on the unsteady flow measurement.
