Abstract
In this paper, we measure the surface pressure distribution of a rotating fan using a silica nanoparticle pressure-sensitive paint (PSP), which is a sprayable fast-responding PSP. In order to compensate the temperature sensitivity of the PSP, we simultaneously measure the temperature distribution using a polymer-based temperature sensitive paint (TSP). The experimental results show that, in order to obtain small variety of pressure distribution, the raw images of actual (rotating) condition must be adjusted to the image of reference (still) condition within one pixel. Non-uniform distribution of residual moisture content in PSP layer disturbs the accurate pressure measurement.
