A Predictor-Corrector Scheme for Conservation Equations with Discontinuous Coefficients

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
In this paper we propose an explicit predictor-corrector finite difference scheme to numerically solve one-dimensional conservation laws with discontinuous flux function appearing in various physical model problems, such as traffic flow and two-phase ...

High-Resolution Finite Compact Difference Schemes for Hyperbolic Conservation Laws [PDF]

open access: yes, 2006
A finite compact (FC) difference scheme requiring only bi-diagonal matrix inversion is proposed by using the known high-resolution flux. Introducing TVD or ENO limiters in the numerical flux, several high-resolution FC-schemes of hyperbolic conservation ...

Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]

open access: yes, 2013
We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

Finite difference method for time-space-fractional Schrödinger equation

open access: yes, 2015
In this paper, an implicit finite difference scheme for the nonlinear time-space-fractional Schrödinger equation is presented. It is shown that the implicit scheme is unconditionally stable with experimental convergence order of O(τ2−α+h2), where τ and h

New Second-Order Finite Difference Scheme for the Problem of Contaminant in Groundwater Flow

open access: yesJournal of Applied Mathematics, 2012
We develop a new efficient second-order finite difference scheme for two-dimensional problem of contaminant in groundwater flow. Theoretical analysis shows that the scheme is second-order convergence in the L2 norm and is unconditionally stable ...

The Structure of Certain Finite Difference Schemes

open access: yesSIAM Review, 1961
where, upon introducing a set of mesh points each identified by an (n + 1 )-tuple of integers K = (Ko , K1 , * * * , Kn), we choose for each non-initial point K a subset of mesh points S(K) not containing K. The scheme represented by (2) will be explicit if the mesh points can be ordered in such a way that points at which initial conditions are given ...

An ALE based hybrid meshfree local RBF-cartesian FD scheme for incompressible flow around moving boundaries

open access: yes
A solution scheme is presented to simulate incompressible viscous flow around moving boundaries using hybrid meshfree-Cartesian grid. The presented solution approach avoids intensive re-meshing and enhances computational efficiency by combining the ...
