Development of dynamic calibration system for high-frequency response evaluation of fast pressure-sensitive paint using cavity-induced flapping jet

A high-frequency dynamic calibration system for pressure-sensitive paint (PSP) was developed using cavity-induced jets. The dominant frequency for dynamic calibration was adjusted to the range of 9–16 kHz by scaling the cavity. The dominant flapping frequencies corresponding to different cavity lengths were identified. The distributions of pressure fluctuations across cavities were measured using fast PSP technology.
