Pore-scale characterization of transverse mixing-induced calcium carbonate precipitation of relevance to geological carbon sequestration
This study examines the reaction between carbonate and calcium to precipitate calcium carbonate in an experimental model. This model is a small micro-fluidic device that incorporates a flow channel with an imprinted homogeneous pore structure to replicate the porous nature of groundwater flow. …

LONGITUDINAL SOLUTE TRANSPORT IN OPEN-CHANNEL FLOW - A Numerical Simulation Study on Longitudinal Dispersion, Surface Storage Effects, Transverse Mixing, Uncertainties and Parameter-Transferring Problems
… average volumetric flow rate; Dt is an average transverse dispersion coefficient; W is the channel flow width), derived from non-dimensionalization of the governing equations of one of the most rigorous 2-dimansional (2D) (depth-averaged) model, Mike21, this work presents an alternative way of …

Analysis of Solute Mixing at the Pore-Scale Using Micromodels and Lattice -Boltzmann Finite Volume Modeling
Transverse mixing has been shown to often be the controlling mechanisms for degradation of contaminants in groundwater. For a conservative contaminant, downgradient concentrations depend on initial source zone concentrations and the extent to which the contaminant mixes (i.e., dilutes) with …

3-D numerical simulation of reactive extrusion and its application to polymerization of ε-caprolactone in co-rotating twin-screw extruders
… extruders is reliable. Three indices, i.e. flux-mixing coefficient, temperature mixing coefficient, and conversion ratio mixing coefficient, are defined for the first time to evaluate the axial mixing during reactive extrusion. Moreover, transverse mixing is characterized with the ratio of …
