Numerical Viscosity and the Entropy Condition for Conservative Difference Schemes
نویسندگان
چکیده
Consider a scalar, nonlinear conservative difference scheme satisfying the entropy condition. It is shown that difference schemes containing more numerical viscosity will necessarily converge to the unique, physically relevant weak solution of the approximated conservative equation. In particular, entropy satisfying convergence follows for E schemes—those containing more numerical viscosity than Godunov's scheme.

The Numerical Viscosity of Entropy Stable Schemes for Systems of Conservation Laws
Discrete approximations to hyperbolic systems of conservation laws are studied. We quantify the amount of numerical viscosity present in such schemes, and relate it to their entropy stability by means of comparison. To this end, conservative schemes which are also entropy conservative are constructed. These entropy conservative schemes enjoy second-order accuracy; moreover, they can be interpre...
متن کاملEntropy Conservative and Entropy Stable Schemes for Nonconservative Hyperbolic Systems
The vanishing viscosity limit of nonconservative hyperbolic systems depends heavily on the specific form of the viscosity. Numerical approximations, such as the path consistent schemes of [C. Parés, SIAM J. Numer. Anal., 41 (2007), pp. 169–185], may not converge to the physically relevant solutions of the system. We construct entropy stable path consistent (ESPC) schemes to approximate nonconse...
متن کاملHigh-Order Schemes, Entropy Inequalities, and Nonclassical Shocks
We are concerned with the approximation of undercompressive, regularizationsensitive, nonclassical solutions of hyperbolic systems of conservation laws by high-order accurate, conservative, and semidiscrete finite difference schemes. Nonclassical shock waves can be generated by diffusive and dispersive terms kept in balance. Particular attention is given here to a class of systems of conservati...
متن کاملPerfect Derivatives, Conservative Differences and Entropy Stable Computation of Hyperbolic Conservation Laws
Entropy stability plays an important role in the dynamics of nonlinear systems of hyperbolic conservation laws and related convection-diffusion equations. Here we are concerned with the corresponding question of numerical entropy stability — we review a general framework for designing entropy stable approximations of such systems. The framework, developed in [28, 29] and in an ongoing series of...
متن کاملEntropy Stable Schemes
We review the topic of entropy stability of discrete schemes, finite-difference and finite-volume schemes, for the approximate solution of nonlinear systems of conservation laws. The question of entropy stability plays an important role in both, the theory and computation of such systems, which is reflected by the extensive literature on this topic. Here we focus on a several key ingredients in...
