Abstract

We extend the framework and the convergence criteria of wavewise entropy inequalitiesof H. Yang [35] to a class of fully-discrete high-resolution schemes for hyperbolic conservationlaws with source terms. This approach is based on an extended theory of Yang [35] on wave trackingand wave analysis and the theory of Vol’pert [33] on BV solutions. For the Cauchy problem of convexconservation laws with source terms, we use one of the criteria to show the entropy convergence ofthe schemes with van Leer’s flux limiter when the building block of the schemes is the Godunovor Engquish–Osher. The entropy convergence of the homogeneous counterparts of these schemes,originally introduced by Sweby [30], were established by the author [17].
