Abstract
The pressure-sensitive paint (PSP) technique is an optical technique for measuring surface pressure on a model surface. The PSP technique has been used in wind-tunnel tests because of its great advantages such as non-intrusive and global pressure measurement. In general, PSP is painted by a sprayer by hand, resulting in low reproducibility. In this study, we used a commercial inkjet printer for printing PSP on substrates. PSP was printed on three substrates: chromatography paper, label seal, and viewgraph. We investigated the pressure and temperature sensitivities of these PSPs. PSP printed on the chromatography paper showed the best characteristics among them. And, we succeeded in preparation of PSP using the commercial inkjet printer.
