Rosalind Reid Executive Director, IIC ******************************************* IIC Colloquium Title: Discretization Kinetic Theory-based Approach for Computational Fluid Dynamics December 10, 2008 at 4:00 p.m. Location: 60 Oxford Street, Room 330 Abstract: It has been nearly two decades since formation of the first lattice Boltzmann (LB) algorithm. By now its physics and mathematic underpinnings provide a solid theoretical base. Furthermore, the approach has evolved from a mere academic toy to a major new branch in computational fluid dynamics (CFD), facilitating real-world application. This talk will give an overview of some fundamentals and clarify essential starting points, emphasizing comparison with traditional Navier-Stokes based CFD. The speaker will also present a rigorous general condition for LB to capture necessarily required non- equilibrium physics properties. This is essential for going beyond the Navier-Stokes based CFD. Finally, the speaker is going to outline some basic advantages in LB, especially for handling complex geometry and performing time-dependent flow simulations, and to present some specific numerical examples. Hudong Chen is currently the Chief Scientist at Exa Corporation based in Burlington, Massachusetts, a scientific software company for computational fluid dynamics applications. Hudong has been leading core technology development at Exa for over ten years. The core technology is based on lattice Boltzmann methods in combination with state of the art turbulence modeling. The software is now been widely used in various industries. Hudong received his Ph.D. in physics from Dartmouth College in 1986. He has done post-doctoral work at Los Alamos National Laboratory and elsewhere, and has collaborated with renowned scientists such as Dr. Robert Kraichnan on turbulence theory. Hudong Chen has been a pioneer and leader in the field of lattice Boltzmann methods. In 2000, he was nominated as a Fellow of the American Physical Society. Currently he is also an Affiliated Professor with the aerospace engineering department at Iowa State University.
