Title High-Order Entropy Stable Finite Difference Schemes for Nonlinear Conservation Laws: Finite Domains.
Publication Date Feb 2013
Media Count 62p
Personal Author M. H. Carpenter T. C. Fisher
Abstract Developing stable and robust high-order finite difference schemes requires mathematical formalism and appropriate methods of analysis. In this work, nonlinear entropy stability is used to derive provably stable high-order finite difference methods with formal boundary closures for conservation laws. Particular emphasis is placed on the entropy stability of the compressible Navier-Stokes equations. A newly derived entropy stable weighted essentially non-oscillatory finite difference method is used to simulate problems with shocks and a conservative, entropy stable, narrow-stencil finite difference approach is used to approximate viscous terms.
