The Armour College of Engineering Department of Chemical and Biological Engineering will sponsor a seminar featuring Dr. Hui Hu from 3:15-4:30 pm on Wednesday, March 12, 2014 in Perlstein Hall Auditorium, Room 131. Hu’s lecture is titled “Investigations of Complex Thermal Fluids Phenomena Using Advanced Flow Diagnostic Techniques.” Hu is a Professor of Aerospace Engineering at Iowa State University with technical background in the field of experimental aerodynamics, fluid mechanics, and heat transfer with emphasis on developing and applying advanced flow diagnostic techniques to study various complex thermal fluids phenomena.
The lecture will describe recent progress in developing a novel molecule-based flow diagnostic technique, Molecular Tagging Velocimetry and Thermometry (MTV&T), used for simultaneous measurements of flow velocity and temperature distributions in fluid flows. Unlike most commonly used particle-based flow diagnostic techniques, MTV&T utilizes specially-designed phosphorescent molecules as tracers for both flow and velocity and temperature measurements. The unique nature of the MTV&T technique will be demonstrated using example applications of the study of thermal effects on the wake instabilities behind a heated cylinder, visualization of the unsteady heat transfer and phase changing process within micro-sized icing water droplets, and transient surface water trasport processes pertinent to aircraft or wind turbine icing and de- / anti-icing applications. The lecture will also present and overview of the speaker’s research on wind turbine aeromechanics and wake interferences.
Hu’s recent research interests include wind energy and wind turbine aeromechanics; icing physics, aircraft and wind turbine anti-icing / de-icing technology; film cooling, trailing edge cooling and thermal management of gas turbine blades; low-speed aerodynamics and vortex flow controls; bio-inspired aerodynamic designs for micro-air-vehicle applications;micro-flows and micro-scale heat transfer in micrfluidics or “lab-on-a-chip” devices; and tornado, microburst wind, and fluid-structure interactions of build structures in violent winds.
