Mass-Transport Models with Fragmentation and Aggregation [PDF]

, 2010
We present a review of nonequilibrium phase transitions in mass-transport models with kinetic processes like fragmentation, diffusion, aggregation, etc. These models have been used extensively to study a wide range of physical problems.

Explosive condensation in a mass transport model [PDF]

, 2012
We study a far-from-equilibrium system of interacting particles, hopping between sites of a 1d lattice with a rate which increases with the number of particles at interacting sites.

Observation of Mass Transport through Solid 4He [PDF]

, 2009
By use of a novel experimental design, one that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the DC transport of mass through a cell filled with solid 4He in the hcp region of the phase diagram. Flow,

Transport Out of the Antarctic Polar Vortex from a Three-dimensional Transport Model [PDF]

, 2002
[1] A three-dimensional chemical transport model is utilized to study the transport out of the Antarctic polar vortex during the southern hemisphere spring.

The Effect of Proton-Exchange Membrane Fuel Cell Configuration Changing from Straight to Cylindrical State on Performance and Mass Transport: Numerical Procedure [PDF]

Journal of Renewable Energy and Environment, 2021
In the present work, a Proton-Exchange Membrane Fuel Cell (PEMFC) as a three-dimensional and single phase was studied. Computational fluid dynamics and finite volume technique were employed to discretize and solve a single set of flow fields and ...

Identifying Deficiencies of Standard Accretion Disk Theory: Lessons from a Mean-Field Approach [PDF]

, 2008
Turbulent viscosity is frequently used in accretion disk theory to replace the microphysical viscosity in order to accomodate the observational need for in- stabilities in disks that lead to enhanced transport. However, simply replacing the microphysical

Study of the effect of ADL anodic diffusion layer on the performance of a direct methanol fuel cell (DMFC)

Revue des Énergies Renouvelables, 2022
In this study we investigated the properties of the species diffusion layer (ADL) affect the optimal performance of the electrode [1]. Diffusion layers (DL) are porous media allowing reactive gases and liquids to move from distribution channels to ...

Groundwater monitoring of an open-pit limestone quarry: Water-rock interaction and mixing estimation within the rock layers by geochemical and statistical analyses

International Journal of Mining Science and Technology, 2018
Water-rock interaction and groundwater mixing are important phenomena in understanding hydrogeological systems and the stability of rock slopes especially those consisting largely of moderately water-soluble minerals like calcite.

Mass-Transport Models with Multiple-Chipping Processes [PDF]

, 2010
We study mass-transport models with multiple-chipping processes. The rates of these processes are dependent on the chip size and mass of the fragmenting site. In this context, we consider k-chip moves (where k = 1, 2, 3, ....); and combinations of 1-chip,
