Analytical Solutions of a Nonlinear Convection-Diffusion Equation With Polynomial Sources

Моделирование и анализ информационных систем, 2016
Nonlinear convection–diffusion equations are widely used for the description of various processes and phenomena in physics, mechanics and biology. In this work we consider a family of nonlinear ordinary differential equations which is a traveling wave ...

A bounded upwinding scheme for computing convection-dominated transport problems

, 2012
A practical high resolution upwind differencing scheme for the numerical solution of convection-dominated transport problems is presented. The scheme is based on TVD and CBC stability criteria and is implemented in the context of the finite difference ...

An Obstacle Problem for Noncoercive Operators

Abstract and Applied Analysis, 2015
We study the obstacle problem for second order nonlinear equations whose model appears in the stationary diffusion-convection problem. We assume that the growth coefficient of the convection term lies in the Marcinkiewicz space weak-LN.

On Local Relaxation Methods and Their Application to Convection-Diffusion Equations [PDF]

, 1981
This paper discusses local relaxation (LR) methods which can be regarded as generalizations of the successive overrelaxation (SOR) method. The difference is that within an LR method the relaxation factor is allowed to vary from equation to equation.

The Improved Element-Free Galerkin Method for 3D Steady Convection-Diffusion-Reaction Problems with Variable Coefficients

Mathematics, 2023
In order to obtain the numerical results of 3D convection-diffusion-reaction problems with variable coefficients efficiently, we select the improved element-free Galerkin (IEFG) method instead of the traditional element-free Galerkin (EFG) method by ...

On the Generalized Fractional Convection–Diffusion Equation with an Initial Condition in ${\mathbb{R}}^{\mathit{n}}$

Fractal and Fractional
Time-fractional convection–diffusion equations are significant for their ability to model complex transport phenomena that deviate from classical behavior, with numerous applications in anomalous diffusion, memory effects, and nonlocality.
