Proper Use of Capillary Number in Chemical Flooding [PDF]

Journal of Chemistry, 2017
Capillary number theory is very important for chemical flooding enhanced oil recovery. The difference between microscopic capillary number and the microscopic one is easy to confuse. After decades of development, great progress has been made in capillary

The rheology of three-phase suspensions at low bubble capillary number. [PDF]

Proc Math Phys Eng Sci, 2015
We develop a model for the rheology of a three-phase suspension of bubbles and particles in a Newtonian liquid undergoing steady flow. We adopt an ‘effective-medium’ approach in which the bubbly liquid is treated as a continuous medium which suspends the particles.

A Brief Review of Capillary Number and its Use in Capillary Desaturation Curves

Transport in Porous Media, 2022
AbstractCapillary number, understood as the ratio of viscous force to capillary force, is one of the most important parameters in enhanced oil recovery (EOR). It continues to attract the interest of scientists and engineers, because the nature and quantification of macroscopic capillary forces remain controversial.

Low-Reynolds-number swimming in a capillary tube [PDF]

Journal of Fluid Mechanics, 2013
AbstractWe use the boundary element method to study the low-Reynolds-number locomotion of a spherical model microorganism in a circular tube. The swimmer propels itself by tangential or normal surface motion in a tube whose radius is of the order of the swimmer size.

A two-angle model of dynamic wetting in microscale capillaries under low capillary numbers with experiments [PDF]

Journal of Colloid and Interface Science, 2018
An accurate model of the dynamic contact angle θd is critical for the calculation of capillary force in applications like enhanced oil recovery, where the capillary number Ca ranges from 10-10 to 10-5 and the Bond number Bo is less than 10-4. The rate-dependence of the dynamic contact angle under such conditions remains blurred, and is the main target ...

Leukocyte margination in alveolar capillaries: Interrelationship with functional capillary geometry and microhemodynamics [PDF]

, 1999
The pulmonary capillary microvasculature harbors a large pool of intravascularly marginated leukocytes. In this study, we investigated the interrelationship of leukocyte margination with characteristics of functional capillary geometry and ...

A HIGHLY STABLE METHYL CELLULOSE COATING FOR CAPILLARY ELECTROPHORESIS

, 1995
A highly stable capillary coating has been created by coupling covalently a hydroxyl group of methyl cellulose to the epoxy group of alpha-glycidoxypropyltrimethoxysilane attached to a piece of fused silica tubing.

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]

, 2012
We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

HYDRODYNAMICS OF A CONFINED MENISCUS IN A SQUARE CAPILLARY TUBE AT LOW CAPILLARY NUMBERS

Frontiers in Heat Pipes, 2014
In microchannel fluid flow, understanding of the liquid-gas interface behavior is vital for developing a wide range of microfluidic devices. The dynamic contact angle of the liquid-air meniscus varies with its velocity and the ensuing meniscus shape has profound effect on the local transport characteristics in its vicinity. Depending on the application,
