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

Chemical Engineering and Processing: Process Intensification, 2009
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.

Axial Dispersion in a Pulsed and Nonpulsed Disc and Doughnut Solvent Extraction Column [PDF]

, 2017
In solvent extraction columns mechanical agitation is usually introduced to improve the extraction efficiency. However, some industrial columns have been found to have higher extraction efficiency while running with no pulsation.

Axial dispersion in biofilters

Biochemical Engineering Journal, 1998
Abstract Biological destruction of toluene vapor from air streams was studied in a laboratory scale biofilter. The packing material (peat) used in the reactor was immobilized with acclimatized bacterial suspension. The original microbial consortium was obtained as an activated sludge suspension from a local waste water treatment plant.

Experimental characterization of axial dispersion in coiled flow inverters [PDF]

Chemical Engineering Research and Design, 2017
Narrow residence time distributions (RTDs) are desirable in many chemical engineering processes. However, when a system operates in the laminar flow regime, significant fluid dynamic dispersion takes place.
