Abstract

Measurements of the surface pressure on a simplified automobile model have been performed using pressure-sensitive paint (PSP). The program was undertaken to investigate the use of commercial and in-house PSP at low speed (between 11 m/s and 92 m/s) and to find techniques to improve the measurement accuracy. A comparison of a priori and in situ calibration methods was also conducted. A linear in situ calibration or a priori methods combined with one tap pressure, correcting for bias errors, were found to provide the best accuracy.
