  Prof. Hui Hu of Iowa State University visited LTCS

Recently, Prof. Hui Hu visited the State Key Laboratory for Turbulence and Complex Systems (LTCS) and dicussed with the laboratory on advanced measurement techniques. Dr. Hui Hu is the Martin C. Jischke Professor in Aerospace Engineering at Iowa State University. Dr. Hu’s recent research interests include laser-based flow diagnostics, aircraft icing physics and anti-icing/de-icing technology; film cooling and thermal management of gas turbines; wind turbine aerodynamics and rotorcraft aeromechanics; low-speed aerodynamics and vortex flow controls; bio-inspired aerodynamics; micro-flows and micro-scale heat transfer in microfluidics or “Lab-on-a-Chip” devices.  Dr. Hu received several prestigious awards in recent years, including 2006 NSF-CAREER Award, 2007 Best Paper in Fluid Mechanics Award (Measurement Science and Technology, IOP Publishing), 2009 AIAA Best Paper Award in Applied Aerodynamics, 2012 Mid-Career Achievement in Research Award of Iowa State University, 2013 AIAA Best Paper Award in Ground Testing Technology, and 2014 Renewable Energy Impact Award of Iowa Energy Center.

  During his visit, Prof. Hu first introduced the description of the recent progress on a novel molecule-based flow diagnostic technique, named as Molecular Tagging Velocimetry and Thermometry (MTV&T), for simultaneous measurements of flow velocity and temperature distributions in fluid flows. Unlike most commonly-used particle-based flow diagnostic techniques such as Particle Image Velocimetry (PIV), MTV&T utilizes specially-designed phosphorescent molecules, which can be turned into long-lasting glowing marks upon excitation by photons of appropriate wavelength, as the tracers for both flow velocity and temperature measurements. Prof. Hu also introduced the recent research on wind turbine aeromechanics and wake interferences in onshore and offshore wind farms. The experimental studies are conducted in a large-scale Aerodynamic/Atmospheric Boundary Layer (AABL) Wind available at Iowa State University. Prof. Hui Hu will continue to visit and discuss research progress and further collaboration with LTCS.
