MONOTONE DIFFERENCE SCHEMES ON NON-UNIFORM GRIDS FOR 2D QUASI-LINEAR PARABOLIC CONVECTION–DIFFUSION EQUATION
Abstract
Abstract. The present paper is devoted to the construction of monotone difference second-order schemes for local approximation on non-uniform grids in space for 2D quasi-linear parabolic convection–diffusion equation. Two-sided estimates of the difference solution are found and an important a priori estimate in a uniform norm C is proved.
