Xiaofeng Liu, Ph.D, Professor of Aerospace Engineering, SDSU.

ABSTRACT:

This talk presents an overview of the research activities being conducted at the
Laboratory of Advanced Experimental Fluid Dynamics at San Diego State University (SDSU).
The mission of the laboratory is to provide world-class professional training to both
undergraduate and graduate students through rigorous cutting-edge research programs in
experimental fluid mechanics. The unique strength of the lab resides in the novel
non-intrusive pressure measurement techniques and their applications in research fields
such as turbulence, bio-fluid dynamics and bio acoustics, unsteady aerodynamics and
fluid-structure interactions. Corresponding to the above research areas, four featuring
research projects, including (1) “Direct measurement of all components of pressure-related
terms in Reynolds stress transport equation budget for a cavity shear layer flow”(2)
“Towards Smart Stethoscope: Correlation between lung internal airway pathological geometry
change and the auscultation signal response”; (3) “Bluff body unsteady aerodynamic force
reduction using surface perforation”; and (4) “Characterization of the unsteady hydrodynamic
force loading on an artificial coral reef structure”, will be reviewed in the talk after a
brief introduction to the non-intrusive pressure field measurement technique and its latest
development at SDSU. Along with the review, the capabilities of the newly built SDSU water
tunnel will also be presented.

Short Bio: Dr. Xiaofeng Liu, an associate fellow of the American Institute of Aeronautics and
Astronautics (AIAA), is currently an assistant professor at the Department of Aerospace
Engineering at San Diego State University. Before joining SDSU, he was first a postdoctoral
fellow, and subsequently an assistant research scientist and adjunct principal research
engineer at the Department of Mechanical Engineering at Johns Hopkins University. He received
his Bachelor and Master degrees in aerodynamics from Beijing University of Aeronautics and
Astronautics, and a Ph.D. degree in aerospace engineering from University of Notre Dame.
Prior to coming to the U.S. for his Ph.D. studies, he was a lecturer at the Department of
Engineering Mechanics at Tsinghua University. Before joining the Tsinghua faculty, he was
a project manager involved in satellite launch services at the Division of International
Cooperation at the China Academy of Launch Vehicle Technology. Dr. Liu has extensive
experience in flow diagnostics including hotwire, seven-hole probe, laser Doppler velocimetry
and Particle Image Velocimetry. His research expertise includes high-lift aerodynamics,
turbulent shear layer flows, wake flows, vortex dynamics, cavitation, flow-structure
interactions, acoustics, evaporative cooling and heat transfer, image processing, and
development of optics-based pressure field measurement techniques. Dr. Liu has been an
Office of Naval Research Summer Faculty Fellow in 2016, 2018 and 2019, respectively.
