High-Speed Camera for High-Speed Flows
Abstract
A High-Speed Camera for High-Speed FlowsWe are seeking DURIP funds for a high-speed camera that will impact several high-speed fluidsresearch programs at the University of Notre Dame. Specifically, a monochrome Vision ResearchPhantom v2512 offers the desired performance: 1280x800 spatial resolution, 25,700-Hz frame ratefor the full frame, and 72-GB memory. The camera will have the optional 2-TB ~CineMag~memory and ~FAST~ shutter package, enabling quick turn-around between tests and improvedsynchronization with pulsed illumination, respectively. The investigators are affiliated with theNotre Dame Institute for Flow Physics and Control, which provides a dedicated infrastructure ofresearch facilities, instrumentation, and full-time technical staff. Several novel investigations willbecome possible by virtue of this DURIP award. Prof. Juliano will use it as the basis for a wavefrontsensor to probe hypersonic boundary-layer instabilities, in a background oriented schlierento examine the complex shock structure of hypersonic finned vehicles, and with high-speedpressure sensitive paint to correlate the phenomena of hypersonic boundary-layer separation. Prof.Gordeyev will be able to perform adaptive optics in real time in both ground- and flight-testenvironments, as well as other experiments requiring two or more high-speed cameras. Prof.Sakaue will be able to perform unsteady surface pressure measurements of shock-shock and shockstructureinteractions over an aerodynamic object in hypersonic flow. Prof. Thomas will utilizethe high-speed camera in flow control experiments focused on drag reduction in compressibleturbulent boundary layers.
