Efficient solver for a special class of convection-diffusion problems
We describe an exact and highly efficient numerical algorithm for solving a special but important class of convection-diffusion equations. These equations occur in many problems in physics, chemistry, or biology, and they are usually hard to treat due to

Matrix-equation-based strategies for convection-diffusion equations
We are interested in the numerical solution of nonsymmetric linear systems arising from the discretization of convection-diffusion partial differential equations with separable coefficients and dominant convection.

Dead Cores in a Convection-Diffusion Problem
A model for fiber spinning is considered. It involves the compressible gas flow through a cylindrical multifilament bundle of parallel fibers. The volume occupied by the bundle is modelled as a porous medium with anisotropic permeability, and the flow is governed by Darcy's law.

Finite Volume Solutions of Convection-Diffusion Test Problems [PDF]
The cell-vertex formulation of the finite volume method has been developed and widely used to model inviscid flows in aerodynamics: more recently, one of us has proposed an extension for viscous flows. The purpose of the present paper is two-fold: first we have applied this scheme to a well-known convection-diffusion model problem, involving flow round

Improving the worthiness of the Elder problem as a benchmark for buoyancy driven convection models [PDF]
An important trapping mechanism associated with the geosequestration of CO~2~ is that of dissolution into the formation water. Although supercritical CO~2~ is significantly less dense than water, experimental data reported in the literature show that the

A New Domain Decomposition Parallel Algorithm for Convection–Diffusion Problem
Basing on overlapping domain decomposition, we construct a new parallel algorithm combined the method of subspace correction with least-squares procedure for solving time-dependent convection–diffusion problem. This algorithm is fully parallel.

A stabilized finite element method for inverse problems subject to the convection-diffusion equation. I: diffusion-dominated regime [PDF]
The numerical approximation of an inverse problem subject to the convection--diffusion equation when diffusion dominates is studied. We derive Carleman estimates that are on a form suitable for use in numerical analysis and with explicit dependence on ...

The disproportionality in the problem parameters of the convection-diffusion-reaction equation may lead to the formation of layer structures in some parts of the problem domain which are difficult to resolve by the standard numerical algorithms ...
