Convergence Improved Lax-Friedrichs Scheme Based Numerical Schemes and Their Applications in Solving the One-Layer and Two-Layer Shallow-Water Equations

Abstract: The first-order Lax-Friedrichs (LF) scheme is commonly used in conjunction with other schemes to achieve monotone and stable properties with lower numerical diffusion. Nevertheless, the LF scheme and the schemes devised based on it, for example, the first-order centered (FORCE) and the slope-limited centered (SLIC) schemes, cannot achieve a time-step-independence solution due to the excessive numerical diffusion at a small time step. In this work, two time-step-convergence improved schemes, the C-FORCE and C-S… Show more

“…Different types of the finite differences schemes are also used to discretized the shallow water equations. Implicit finite difference scheme [12], McCormack schemes [8,9], Lax Friedrichs scheme [33,20], Lax Wendroff [26] and other.In this paper, the unsteady 2D shallow water equations are considered for the simulation of surface flow. These equations are the sets of the nonlinear coupled partial differential equations.…”
