ChBE Department Seminar, Wednesday March 12, 2014

Armour College of Engineering is excited to bring students a seminar presented by Dr. Hui Hu. Dr. Hu’s lecture is titled “Investigations of Complex Thermal Fluids Phenomena Using Advanced Flow Diagnostic Techniques.” This event will be co-sponsored by the ChBE department, Wagner Institute for Sustainable Energy Research (WISER), and the MMAE department.

Abstract

This Lecture will describe recent progress made by the speaker 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 flow, 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 transport processes pertinent to aircraft or wind turbine icing and de-/anti-icing applications. The lecture will also present an overview of the speaker’s research on wind turbine aeromechanics and wake interferences.

Biography:

Dr. Hui Hu is a Professor of Aerospace Engineering at Iowa State University with a technical background in experimental aerodynamics, fluid mechanics, and heat transfer, emphasizing developing and applying advanced flow diagnostic techniques to study various complex thermal fluids phenomena. His 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 microfluidics or “lab-on-a-chip” devices; and tornado, microburst wind, and fluid-structure interactions of build structures in violent winds.
