Using the framework of a new relaxation system, which converts a nonlinear viscous conservation law into a system of linear convection-diffusion equations with nonlinear source terms, a finite variable difference method is developed for nonlinear hyperbolic-parabolic : Mayank Bajpayi, S. V. Raghurama Rao. schemes are represented, as are central and upwind-biased methods, and all are at least second-order accurate. Key words.

Hyperbolic conservation laws, and the Euler equations of compressible ﬂuid dynamics in.

The TVD schemes, originally developed by Harten , are a group of the most popular HRS schemes for solving hyperbolic conservation laws. Generally speaking, depending on some critical conditions (e.g. whether a steep gradient or a discontinuity exists), a TVD flux-limiter often switches from a high-order scheme to a low-order. MAXIMUM-PRINCIPLE-SATISFYING AND POSITIVITY-PRESERVING HIGH ORDER SCHEMES Remark: If we insist on the maximum principle interpreted as m un+1 j M; 8j if m un j M; 8j; where un j is either the approximation to the point value u(xj;tn)for a ﬁnite difference scheme, or to the cell average 1 x Rx j+1=2 xj 1=2 u(x;tn)dxfor a ﬁnite volume or DG scheme, then the scheme can be at most second.
