56th NIA CFD Seminar

Topic: Accuracy-Preserving Boundary Quadrature for Edge-Based Finite-Volume Scheme: Third-order accuracy without curved elements

Date: Tuesday, December 16, 2014

Time: 11:00am-noon (EST)

Room: NIA, Rm137

Speaker: Hiro Nishikawa

Speaker Bio: Dr. Hiroaki Nishikawa is Associate Research Fellow, 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, focusing on hyperbolic methods for robust, efficient, highly accurate viscous discretization schemes.

Abstract: This talk will discuss a third-order edge-based finite-volume scheme on unstructured grids. A general boundary flux quadrature formula is presented, which preserves third-order accuracy of the edge-based scheme at boundary nodes with linear elements. Numerical results show that the scheme achieves third-order accuarcy for a curved boundary problem.
