Journal ArticleDOI
Simulation of multicomponent fluids in complex three-dimensional geometries by the lattice Boltzmann method
TL;DR: It is shown that a first-order phase transition, in three dimensions, may be obtained by this lattice Boltzman method, demonstrating the potential for modeling phase transitions and multiphase flow in porous media.
Journal ArticleDOI
Capillary transport in mortars and concrete
Nicos Martys,Chiara F. Ferraris +1 more
TL;DR: In this paper, a study concerning capillary transport of water in concretes and mortars as a function of water/cement ratio, sand size distribution, and curing is presented.
Journal ArticleDOI
Transport in sandstone: A study based on three dimensional microtomography
Francois M. Auzerais,John H. Dunsmuir,B. B Ferréol,Nicos Martys,John F. Olson,Terizhandur S. Ramakrishnan,Daniel H. Rothman,L. M. Schwartz +7 more
TL;DR: In this paper, high-resolution imaging of the microstructure of Fontainebleau sandstone allows a direct comparison between theoretical calculations and laboratory measurements, and they find that electrical resistivity and wetting phase residual saturation are both overestimated.
Journal ArticleDOI
Virtual permeametry on microtomographic images
TL;DR: In this article, accurate numerical micropermeametry measurements can be performed on 3D digitized images of sedimentary rock, where the sample size can be very small, making it possible to predict properties from core material not suited for laboratory testing (e.g., drill cuttings, sidewall core and damaged core plugs).
Journal ArticleDOI
Universal scaling of fluid permeability for sphere packings
TL;DR: Results from the numerical simulation of Stokes flow through random packings of nonoverlapping or overlapping sphers and a [ital scaling] [ital ansatz] are used to obtain universal curves for the fluid permeability.
