Abstract |
In this paper, we give a convergence analysis of a backward semi-Lagrangian scheme in a finite difference method for Burgers' equation. We apply an iteration free error correction method to solve characteristic curves of particles. We also adopt BDF2 and second order central difference method in time and space, respectively, for the time dependent diffusion equation along the characteristic curves.In the sense of the discrete ℓ-norm, we show that the proposed scheme has the convergencebehavior O(h + Δx + Δ , where h, Δx, and are the time, spatial grid size, and the order of interpolations, respectively.A numerical test is provided to support the validity of the theoretical estimates.
