Pressure sensitive paints are widely used in many applications. The pressure distribution on surfaces obtained by the paint shows good agreement with that by other methods, like a pressure tap. Recently, the paint has been adopted to high Knudsen number flows, such as rarefied gas flows and micro/nano flows. The mechanism of the paint is based on the oxygen quenching of luminescent molecules in the paint. Usually the static pressure is inversely proportional to the luminescent intensity of the paint, because of the static gas condition. In high Knudesen number flows, it is not clear whether this relation holds or not. Here, in this study, we tried to relate the number flux of oxygen molecules and the pressures to the luminescence intensity, and clarify the limit of application in high Knudsen number flows.
