ONR Distinguished Lecture Series:
"Seeking Simplicity in the Flows of Complex Fluids"
Dr. Howard A. Stone
Professor in Mechanical and Aerospace Engineering and Department Chair, Princeton University
Fluid mechanics is a discipline with rich phenomena, spanning a wide range of laminar and turbulent flows, instabilities, and applications in industry, nature, and biology and medicine. The subject of “complex fluids” refers to flows where the complexity is introduced by the presence of suspended particles (e.g. cells, polymers), multiple phases, and includes soft boundaries, electrokinetic effects, etc. These problems naturally link the subject of fluid mechanics to many science and engineering disciplines. I will provide examples of our work highlighting (i) new features of classical instabilities triggered by changes in geometry, (ii) multiphase flows relevant to the design of liquid-infused substrates
exhibiting effective slip, (iii) unexpected dynamics in flow at a T-junction, and (iv) a new approach for membraneless filtration of aqueous solutions, which suggests a potential technology and use in resource-poor settings. The results will be illustrated by a variety of pictures and videos from experiments and simulations, with brief remarks about available quantitative understanding.
This event is now closed. Watch a video of Dr. Stone's lecture.

About Dr. Howard A. Stone
Howard A. Stone received the Bachelor of Science degree in Chemical Engineering from the University of California at Davis in 1982 and the PhD in Chemical Engineering from Caltech in 1988. Following a postdoctoral year in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, in 1989 Dr. Stone joined the faculty of the (now) School of Engineering and Applied Sciences at Harvard University, where he eventually became the Vicky Joseph Professor of Engineering and Applied Mathematics. In July 2009 Dr. Stone moved to Princeton University where he is Donald R. Dixon ’69 and Elizabeth W. Dixon Professor in Mechanical and Aerospace Engineering and Department Chair.
Dr. Stone's research interests are in fluid dynamics, especially as they arise in research and applications at the interface of engineering, chemistry, physics, and biology. He received the NSF Presidential Young Investigator Award, is a Fellow of the American Physical Society (APS), and is past Chair of the Division of Fluid Dynamics of the APS. He is the first recipient of the G.K. Batchelor Prize in Fluid Dynamics, which was awarded in August 2008. He was elected
to the National Academy of Engineering in 2009, the American Academy of Arts and Sciences in 2011 and the National Academy of Sciences in 2014.
