An Optimization Study of PSP Measurement System Characteristics
PSP technique (Pressure Sensitive Paint) as an optical method enables measurement of surface pressure distribution over a model and its measurement system plays an important role in the PSP technique. In the present study, a set of PSP measurement system is established by authors selves and the fluorescent PSP is used Influence of the measurement system characteristics on calibration curves is then explored through much PSP calibration experiments. With five camera aperture and two UV lamp powers, the original PSP calibration images and curves are presented in this paper. The experimental results demonstrated that: (1) characteristics of PSP measurement system have an important effect on the pressure measurement; (2) the 400W UV lamp can provide the adequate excitation photons to excite fluorescence molecules entering the energy transition and a larger CCD aperture can be used to improve the SNR of CCD.
