Assessment of the peripheral microcirculation using computer-assisted venous congestion plethysmography in post-traumatic complex regional pain syndrome type I [PDF]

open access: yes, 2001
In complex regional pain syndrome type I (CRPS-I), edema of the affected limb is a common finding. Therefore, the changes in macro- and microcirculatory parameters were investigated to elucidate the underlying pathophysiology.

The correlation of the steady-state gas/water relative permeabilities of porous media with gas and water capillary numbers

open access: yesOil & Gas Science and Technology, 2019
The steady-state gas, k rg, and water, k rw, relative permeabilities are measured with experiments of the simultaneous flow, at varying flow rates, of nitrogen and brine (aqueous solution of NaCl brine) on a homogeneous sand column.

High accuracy capillary network representation in digital rock reveals permeability scaling functions

open access: yesScientific Reports, 2021
Permeability is the key parameter for quantifying fluid flow in porous rocks. Knowledge of the spatial distribution of the connected pore space allows, in principle, to predict the permeability of a rock sample. However, limitations in feature resolution

Transport of polymer particles in a oil-water flow in porous media: enhancing oil recovery [PDF]

open access: yes, 2018
We study a heuristic, core-scale model for the transport of polymer particles in a two phase (oil and water) porous medium. We are motivated by recent experimental observations which report increased oil recovery when polymers are injected after the ...

Permeabilities of Water–Oil Two-Phase Flow in Capillary Fractures with Different Wettabilities

open access: yesEnergies
The influence of wettability on the permeability performance of water–oil two-phase flow has attracted increasing attention. Dispersed flow and stratified flow are two flow regimes for water–oil two-phase flow in capillary fractures.
