A remote surface pressure measurement technique for rotating elements
- Univ. of Florida, Gainesville, FL (United States)
This technical note describes a photoluminescent paint technique developed to measure the steady-state surface pressure distributions on rotating elements. The application of pressure-sensitive paints (PSPs) as a means of measuring surface pressure has emerged in recent years as a viable alternative to conventional transducers, yielding accurate quantitative results (Morris et al., 1993; McLachlan et al., 1993; Morris, 1995). Burns and Sullivan (1995) describe a lifetime-based technique to measure pressure on rotating machinery with tip speeds exceeding 200 m/s. Their method measures the phase shift that occurs between a modulated excitation source and the corresponding emission response of the paint. The technique performed in this paper uses an unmodulated light source and measures the actual intensity decay with respect to time. The corresponding lifetimes of decay are then calibrated with the steady-state pressure.
