Stability analysis and numerical results for some schemes discretising 2D nonconstant coefficient advection–diffusion equations

Autor: Appadu Appanah Rao, Gidey Hagos Hailu

Publikováno v: Open Physics, Vol 22, Iss 1, Pp 77-102 (2024)

We solve two numerical experiments described by 2D nonconstant coefficient advection–diffusion equations with specified initial and boundary conditions. Three finite difference methods, namely Lax–Wendroff, Du-Fort–Frankel and a nonstandard fin

Some standard and nonstandard finite difference schemes for a reaction–diffusion–chemotaxis model

Autor: de Waal Gysbert Nicolaas, Appadu Appanah Rao, Pretorius Christiaan Johannes

Publikováno v: Open Physics, Vol 21, Iss 1, Pp 1071-82 (2023)

Two standard and two nonstandard finite difference schemes are constructed to solve a basic reaction–diffusion–chemotaxis model, for which no exact solution is known. The continuous model involves a system of nonlinear coupled partial differentia

Comparison of modified ADM and classical finite difference method for some third-order and fifth-order KdV equations

Autor: Appadu Appanah Rao, Kelil Abey Sherif

Publikováno v: Demonstratio Mathematica, Vol 54, Iss 1, Pp 377-409 (2021)

The KdV equation, which appears as an asymptotic model in physical systems ranging from water waves to plasma physics, has been studied. In this paper, we are concerned with dispersive nonlinear KdV equations by using two reliable methods: Shehu Adom

Numerical solution of a malignant invasion model using some finite difference methods

Autor: Appadu Appanah Rao, Waal Gysbert Nicolaas de

Publikováno v: Demonstratio Mathematica, Vol 56, Iss 1, Pp 389-33 (2023)

In this article, one standard and four nonstandard finite difference methods are used to solve a cross-diffusion malignant invasion model. The model consists of a system of nonlinear coupled partial differential equations (PDEs) subject to specified
