Flow Through a Laboratory Sediment Sample By Computer Simulation Modeling
Physics and Astronomy
A laboratory sediment sample is digitized by X-ray computed tomography system to obtain a host matrix of size 1003 of porosity 0.282. Flow through the porous medium is studied by an interacting lattice gas model for fluid driven by pressure bias. The bias H(0 <= H <= 1) is implemented via soft and hard pressure constraints in selecting the stochastic movement of fluid particles. The response of fluid flux density to bias H is nearly linear with soft pressure; it becomes nonmonotonic with the hard pressure. (c) 2006 Elsevier B.V. All rights reserved.
