A Backward Semi-Lagrangian Scheme for Coupled Burgers' Equation

Abstract
This paper is intended as an application of backward semi-Lagrangian scheme combined with the error correction method to obtain numerical solutions for nonlinear coupled Burgers' equation. To linearize the nonlinear diffusion-reaction system resulted from the backward semi-Lagrangian process, we develop a type of extrapolation scheme without the damaging of temporal accuracy. Through the numerical simulations of the targeted equations, we demonstrate the proposed method has the second-order convergence rates in time and space. In addition, our numerical results are in good agreement with the analytic solution and offer better accuracy in comparison with other existing scheme.
