Using a two-zone moment analysis (TZMA) method based on Brenner's generalized
dispersion theory for two-dimensional (2D) and three-dimensional (3D) periodic media, we …

For liquids used in biological applications, a smaller diffusion coefficient results in a longer
mixing time. We discuss, in this endeavor, the promising potential of the AC electrothermal …

We report on a new homogenization approach to solve, with drastically improved speed and
accuracy, the general advection-diffusion equation in hierarchical porous media with …

The efficiency of liquid chromatography separations could be strongly improved by changing
the current packed bed columns by a bundle of parallel capillary tubes. In practice, however …

We have developed a theoretical framework to characterize the transport and mixing of a
passive scalar in a capillary tube. In this configuration, a suspension of magnetic …

Abstract Open-Tubular Liquid Chromatography (OTLC) is currently limited by two
shortcomings, namely the low ratio of adsorbing area to the channel volume and the large …

The Lagrangian transport in the laminar incompressible flow in a two-dimensional square
cavity driven by a harmonic tangential oscillation of the lid is investigated numerically for a …

Axial dispersion in chromatographic columns is responsible for a reduced separation
efficiency. In the present research macrotransport theory is used to predict the …

We investigate band broadening in the most widely adopted configuration of micro-pillar
array columns (μ PACs)—specifically, a cylindrical pillar array where both the pillar walls …

The exact moment method for the determination of the dispersion tensor in retentive porous
media has been adopted to compute the dispersion coefficients, the plate height curves and …
