Description

Pressure-Sensitive Paint (PSP) is an exceptional tool used to gather the pressure distribution on a model during a wind tunnel test (or other similar methods of testing) in the form of a high-resolution image. In order to use the PSP effectively, however, an intimate understanding of the paint being employed must first be established and the reaction time of the paint being developed must be pushed to the limit. These goals in my work are accomplished by sending various novel PSP creations through a resonance tube that was designed, constructed, and applied here on campus. The resonant qualities of an air column in the tube are exploited to increase the magnitude of the rapid pressure fluctuations coming from a speaker system. The pressure readings from the paint inside the tube will be compared to the more exact results from a pressure transducer to determine the frequency response time of the paint, thus allowing the testing of novel PSP at any desired frequency range between 0 and 60 kHz.
