Talk Title: Advances in Advancing Interfaces: The Mathematics of Manufacturing of
Industrial Foams, Fluidic Devices, and Automobile Painting
Abstract: How do inkjet printers work? What are the dynamics of a dripping faucet? How are foams mixed, bicycle helmets manufactured, and cars painted? Complex dynamics underlying industrial manufacturing depend in part on multiphase multiphysics, in which fluids and materials interact across orders of magnitude variations in time and space. In this talk, we will discuss the development and application of a host of numerical methods for these problems, including Level Set Methods, Voronoi Implicit Interface Methods, implicit adaptive representations, and multiphase discontinuous Galerkin Methods. Applications for industrial problems will include modeling how foams evolve, how electro-fluid jetting devices work, and the physics and dynamics of rotary bell spray painting across the automotive industry.
James Sethian is a professor of Mathematics in the Department of Mathematics at the University of California, Berkeley, and the Head of Mathematics Group at the Lawrence Berkeley National Laboratory and a fellow of the American Mathematical Society. He is a world-renowned applied mathematician, recognized for his work on computational physics and the theory, algorithms, and applications of moving interfaces as they are applied to problems in fluid mechanics, materials science, and industrial processes. His work has also had great impact on the fields of combustion, tomography, industrial foams, and medical image analysis.
Sethian received his doctorate from Berkeley in 1982 under the direction of Alexandre Chorin, after which he became postdoctoral fellow at the Courant Institute, before returing to Berkeley in 1985. As a .member of the National Academy of Engineering, is the recipient of numerous prizes and awards, including the Norbert Wiener Prize in Applied Mathematics, which is awarded jointly by the American Mathematical Society and the Society for Industrial and Applied Mathematics, "for an outstanding contribution to applied mathematics in the highest and broadest sense." Specifically, he was recognized for his representations of the motion of curves, surfaces, interfaces, and wave fronts, and for his applications of mathematical and computational ideas to scientific problems. In 2011 he was awarded the ICIAM Pioneer Prize Pioneer Prize, for his contributions to applications in imaging and shape recovery in medicine, geophysics, tomography, and drop dynamics in inkjets. In 2012, Sethian, along with collaborator Robert Saye won the Cozzarelli Prize for the best paper published in the Proceedings of the National Academy of Sciences in the area of engineering and applied sciences.
