Bi-luminophore Coatings for Temperature Correction of Pressure-Sensitive Paint Measurement

Pressure-Sensitive Paint (PSP) allows us to measure pressure images on a model in high spatial resolution. It is a useful measurement tool for understanding aerodynamics on a whole model of an aerospace vehicle, a car and a train in the wind tunnel tests. However, PSP has a temperature dependency of its luminescent intensity. Thereby, temperature correction of PSP should be done to measure accurately pressure images. This paper reported the latest study of temperature correction of PSP measurement using bi-luminophore coatings.
