Flow Through a Laboratory Sediment Sample by Computer Simulation Modeling

Pagination or Media Count:
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 H0 less than or equal to H less than or equal to 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.
