Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]
Chemical Engineering and Processing: Process Intensification, 2009 Abstract The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear-thinning non-Newtonian flow using computational fluid dynamics. The results reveal that for a fixed cross-sectional area and throughput, there is a narrowing

Use of the Dispersion Coefficient as the Sole Structural Parameter to Model Membrane Chromatography
Membranes, 2022 The characterization and modelling of membrane chromatography processes require the axial dispersion coefficient as a relevant and effective intrinsic property of porous media, instead of arbitrary assumptions on pore size distribution.
