Hydrodynamic Dispersion in Porous Media and the Significance of Lagrangian Time and Space Scales

open access: yesFluids, 2020
Transport in porous media is critical for many applications in the environment and in the chemical process industry. A key parameter for modeling this transport is the hydrodynamic dispersion coefficient for particles and scalars in a porous medium ...

Short-time rotational diffusion in monodisperse charge-stabilized colloidal suspensions

open access: yes, 1996
We investigate the combined effects of electrostatic interactions and hydrodynamic interactions on the short-time rotational self-diffusion coefficient in charge-stabilized suspensions.

Pair diffusion, hydrodynamic interactions, and available volume in dense fluids

open access: yes, 2012
We calculate the pair diffusion coefficient D(r) as a function of the distance r between two hard-sphere particles in a dense monodisperse suspension.

Diffusion of a sphere in a dilute solution of polymer coils

open access: yes, 2009
We calculate the short time and the long time diffusion coefficient of a spherical tracer particle in a polymer solution in the low density limit by solving the Smoluchowski equation for a two-particle system and applying a generalized Einstein relation (

Effect of surfactants on liquid side mass transfer coefficients: a new insight [PDF]

open access: yes, 2009
Specific experiments are proposed to investigate the effect of surfactants on liquid side mass transfer coefficients. They are based on the determination of the liquid side mass transfer coefficient kL at a free gas-liquid interface, under controlled ...

Hydrodynamic field driving effect and mathematical model construction of water quality formation and evolution in coal mine

open access: yesMeitan xuebao, 2023
The change of regional hydrodynamic field caused by coal mining process affects the multi-field process of the formation and evolution of mine water quality, which may lead to the pollution of the water environment in the coal mining area.

Collective diffusion coefficient of proteins with hydrodynamic, electrostatic and adhesive interactions

open access: yes, 2007
A theory is presented for lambda_C, the coefficient of the first-order correction in the density of the collective diffusion coefficient, for protein spheres interacting by electrostatic and adhesive forces.

The sound damping constant for generalized theories of gravity [PDF]

open access: yes, 2009
The near-horizon metric for a black brane in Anti-de Sitter (AdS) space and the metric near the AdS boundary both exhibit hydrodynamic behavior. We demonstrate the equivalence of this pair of hydrodynamic systems for the sound mode of a conformal theory.

Experimental study on hydrodynamic characteristics of a taut moored floating box

open access: yesFrontiers in Mechanical Engineering
To investigate the hydrodynamic capabilities of the floating breakwater with a taut mooring system, a two-dimensional physical modelling experiment was performed to investigate the hydrodynamic characteristics of the hydrodynamic pressure on the front ...
