Hirotaka Sakaue, associate professor in the Department of Aerospace and Mechanical Engineering, was the featured speaker at the March 20 NDnano networking lunch for affiliated faculty and staff. The Sakaue Lab combines fluid mechanics and chemistry in four signature areas: flow measurement, flow control (chemical flow control), bio/biomedical, and green energy/environment.
Professor Sakaue’s presentation was entitled, “Phosphor-based Luminescent Sensor for High-Speed Aerodynamics.” His team investigated the properties of thermographic phosphors in the high-temperature region from 100°C to 800°C. These thermographic phosphors must have sufficiently high-temperature sensitivity and luminescence intensity in the test temperature range, and the phosphor binder must be strong enough to withstand supersonic flow and high-temperature environments. Dr. Sakaue presented his team’s most recent results with these high-temperature phosphor sensors. He then opened the session up to the audience for suggestions for other phosphors and ideas for other applications of these phosphor sensors.
NDnano sponsors monthly networking meetings to provide a forum for faculty and staff to discuss recent research, probe new ideas, and connect with new collaborators. Notre Dame faculty and staff are invited to attend and join in the discussion to learn and advance research at Notre Dame. Visit the NDnano events page to learn about future networking sessions.
