This research aims to register luminescence images obtained in a pressure-sensitive paint (PSP) measurement by using PSP and temperature-sensitive paint (TSP) dots in the dual-array sensor as markers. This reduces measurement error caused by position difference between obtained images in a PSP measurement without any additional markers. In this research, pressure and temperature distributions caused by a jet impingement was measured the dual-array sensor. We detected geometric centers of each PSP and TSP dot, interpolated the dot images, and registered the interpolated PSP and TSP images by the projective transformation. Obtained pressure distribution by this method qualitatively well agreed with the distribution which was interpolated after calculating each pressure value at each dot position.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
