Abstract: Fluid dynamics is a discipline with a long history and has a distinctive feature that it links engineering, mathematics, and physics and provides many avenues for intersections with biology. In this talk Dr. Howard Stone will provide one view of the ways that mechanics, and in particular fluid dynamics, yields insights into a wide variety of "multiphase" problems. The examples will include fluid motions generated by living organisms, flows influenced by surface micro textures, various examples involving bacteria, biofilms and flows, bubbly flows that yield insights into unappreciated single-phase flow complexity in simple geometries, and finally the use of a physicochemical phenomenon, "diffusiophoresis", that suggest new approaches to membraneless filtration of particulate solutions.
About the speaker: Howard Stone received a Bachelor of Science degree in Chemical Engineering from UC Davis in 1982 and a PhD in Chemical Engineering from Caltech in 1988. From 1989-2009 he was a professor in the School of Engineering and Applied Sciences at Harvard University and now is Donald R. Dixon ’69 and Elizabeth W. Dixon Professor in Mechanical and Aerospace Engineering at Princeton University. He was the first recipient of the G.K. Batchelor Prize in Fluid Dynamics, which was awarded in August 2008. He is a Fellow of the American Physics Society (APS), past Chair of the Division of Fluid Dynamics of the APS, and is a member of the American Academy of Arts and Sciences, the National Academy of Engineering, and the National Academy of Sciences of the USA. Related to teaching, in 1994 he received both the Joseph R. Levenson Memorial Award and the Phi Beta Kappa teaching Prize, which are the only two teaching awards given to faculty in Harvard College, and in 2000 he was named a Harvard College Professor for his contributions to undergraduate education. In 2017 he received the Presidential Award for Distinguished Teaching at Princeton University.
