| Abstract | A class of numerical dissipation models for central-difference schemes constructed with secondand fourth-difference terms is considered. The notion of matrix dissipation associated with upwind schemes is used to establish improved shock capturing capability for these models. In addition, conditions are given that guarantee that such dissipation models produce a TVD scheme. Appropriate switches for this type of model to ensure satisfaction of the TVD property are presented. Significant improvements in the accuracy of a centraldifference scheme are demonstrated by computing both inviscid and viscous transonic airfoil flows. ';iozi For |
