The finite difference scheme for mathematical modeling of wood drying process

open access: yesMathematical Modelling and Analysis, 2001
This work discusses issues on the design of finite difference schemes for modeling the moisture movement process in the wood. A new finite difference scheme is proposed.

H4 exponential finite-difference scheme for convective diffusion-equations

open access: yes, 1992
Perturbations are applied to the convective coefficients and source term of a convection-diffusion equation so that second-order corrections may be applied to a second-order exponential scheme. The basic Structure of the equations in the resulting fourth-

Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]

open access: yes, 1995
An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

ON FINITE DIFFERENCE SCHEMES FOR THE 3-D WAVE EQUATION USING NON-CARTESIAN GRIDS

open access: yes, 2013
In this paper, we investigate finite difference schemes forthe 3-D wave equation using 27-point stencils on the cubiclattice, a 13-point stencil on the face-centered cubic (FCC)lattice, and a 9-point stencil on the body-centered cubic(BCC) lattice.

Backward difference replacements of the space derivative in first order hyperbolic equations

open access: yes, 1983
Two families of two-time level difference schemes are developed for the numerical solution of first order hyperbolic partial differential equations with one space variable.
