A Simple Method for the Estimation of the Axial Dispersion Coefficient in Gas Flow

open access: yesJournal of Applied Fluid Mechanics, 2018
A simple method which is suitable for determining with reasonable precision the parameters of gas flow system has been proposed. An inverse boundary-value problem is considered.

Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]

open access: yesChemical 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

open access: yesMembranes, 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.

Modeling ofMixing in The Liquid Phase For Bubble Column [PDF]

open access: yesEngineering and Technology Journal, 2009
Hydrodynamic characteristics (mixing in the liquid phase) in a bubble column with a non-Newtonian liquid phase (aqueous solutions of carboxymethylcellulose, or CMC, at different concentrations) were measured and correlated.
