Discretization of the 2D Convection–Diffusion Equation Using Discrete Exterior Calculus [PDF]
Journal of Applied and Computational Mechanics, 2020 While the Discrete Exterior Calculus (DEC) discretization of the diffusive term of the Transport Equation is well understood, the DEC discretization of the convective term, as well as its stabilization, is an ongoing area of research.

A survey of numerical schemes for transportation equation [PDF]
E3S Web of Conferences, 2021 The convection-diffusion equation is a fundamental equation that exists widely. The convection-diffusion equation consists of two processes: diffusion and convection. The convection-diffusion equation can also be called drift-diffusion equaintion.

Equivalence between volume averaging and moments matching techniques for mass transport models in porous media. [PDF]
, 2010 This paper deals with local non-equilibrium models for mass transport in dual-phase and dual-region porous media. The first contribution of this study is to formally prove that the time-asymptotic moments matching method applied to two-equation models is

Transport Equations and Criteria for Active Transport [PDF]
American Zoologist, 1970 The relation between driving forces and the flux of solutes that would be expected in a passive system is derived. This relation is a differential equation and different solutions are obtained which apply to different experimental conditions. Solutions are given for the cases of pure convective flow, diffusion, electrophoretic mobility, balance between
