Convergence of the Generalized Volume Averaging Method on a Convection-Diffusion Problem: A Spectral Perspective [PDF]
, 2005 A mixed formulation is proposed and analyzed mathematically for coupled convection-diffusion in heterogeneous medias. Transfer in solid parts driven by pure diffusion is coupled with convection-diffusion transfer in fluid parts.

Convection in fluid and porous media [PDF]
, 2003 The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

Effects of convection and solid wall on the diffusion in microscale convection flows
, 2010 The diffusive transport properties in microscale convection flows are studied by using the direct simulation Monte Carlo method. The effective diffusion coefficient D is computed from the mean square displacements of simulated molecules based on the ...

Three-dimensional spatially localized binary-fluid convection in a porous medium [PDF]
, 2013 Three-dimensional convection in a binary mixture in a porous medium heated from below is studied. For negative separation ratios steady spatially localized convection patterns are expected.
