22nd NIA CFD Seminar: Divergence Formulation of Source Term

Date: Tuesday, December 4, 2012

Time: 11:00am-noon

Location: NIA, Room 101

Speaker: Hiro Nishikawa

Bio:

Dr. Hiro Nishikawa is Sr. Research Scientist, NIA. He earned Ph.D. in Aerospace Engineering and Scientific Computing at the University of Michigan in 2001. He then worked as a postdoctoral fellow at the University of Michigan on adaptive grid methods, local preconditioning methods, multigrid methods, rotated-hybrid Riemann solvers, high-order upwind and viscous schemes, etc., and joined NIA in 2007. His area of expertise is the algorithm development for CFD, currently focusing on multigrid methods and hyperbolic methods for robust, efficient, highly accurate viscous discretization schemes.

Abstract:

This talk will discuss a simple idea of writing a source term in the divergence form. A conservation law with a source term can then be written in a single divergence form, and consequently it can be discretized by a single scheme without any source term discretization. This talk will focus on its application to the construction of a third-order finite-volume scheme, which requires a special source term discretization but it can be totally avoided by the divergence formulation. Other potential applications and future directions will be discussed.
