New Lax-Friedrichs Scheme for Convective-Diffusion Equation

Abstract: Abstract. Two different types of generalized Lax-Friedrichs scheme for the convective-diffusion equation ut + aux = εuxx(a ∈ R, ε > 0) are given and analyzed. For the convection term, both of two schemes use generalized Lax-Friedrichs scheme. For the diffusion term, explicit central difference scheme is used. The propagation of chequerboard mode is considered for two schemes and several numerical examples are presented only for the first scheme , which display how different parameters control oscillations. For… Show more
