Abstract: 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.
