Скачать или смотреть Guus Jacobs: Marrying Point Particle Methods with Higher-Order Solvers for Conservation Laws

Friday, October 23, 2015
The computation of the interaction between turbulence and finite-sized inertial particles occurs in a wide range of scales and has proven to put heavy demands on computational models. In this talk, I will discuss higher-order Eulerian-Lagrangian models and algorithms that we have recently developed with the aim of improving accuracy and computational efficiency of particle-laden flow computation. I will discuss Eulerian-Lagriangian methods that are based on a combination of particle methods and higher-order methods such as Discontinuous Galerkin methods and WENO methods. Particular attention will be given to the higher-order projection of singular particle methods onto higher-order bases and regularization of interpolation near discontinuities.
Bio:
Professor Jacobs received a M.Sc. in Aerospace Engineering from the Delft University of Technology in 1998, where after graduation, he was appointed to Added Researcher. He received a Ph.D. in Mechanical Engineering from the University of Illinois at Chicago. Following graduation in August of 2003, he was appointed Visiting Assistant Professor in the Division of Applied Mathematics at Brown University. He later combined this position with a Postdoctoral Fellowship at the Department of Mechanical Engineering at the Massachusetts Institute of Technology. As of August 2006 he was appointed Assistant Professor of Aerospace Engineering at San Diego State University and was promoted to Associate and Full Professor and in 2010 and 2014, respectively. He was awarded a University Fellowship at the University of Illinois. He received an AFOSR Young Investigator Award in 2009 and became an Associate Fellow of the American Institute of Aeronautics and Astronautics in 2013. The research interests of Professor Jacobs can broadly be defined in area of computational multiphase, and multi-scale flow physics using high-order methods. Particular emphasis is on simulation, analysis and control of particle-laden flows and flow separation in complex geometries relating to combustion and aerodynamics.
