Numerical comparison of time-accurate algorithms for a nonlinear shock-propagation problem
Abstract
This paper compares the performance of several variations of three finite difference methods for solving a two-dimensional unsteady shock-propagation problem. The primary objectives are to determine the relative merits of explicit and implicit methods, and evaluate upwind schemes relative to central schemes with explicit smoothers. The methods are judged on both accuracy and cost.
