“…Figure 8 shows the saturation profiles for free spontaneous imbibition. We measure a capillary number Ca ≈ 1.5×10 −4 , which agrees with Ca ≈ 10 −6 obtained by Dong et al (1998) and Meleán et al (2003) since they used systems approximately 100 times longer. A water front is visible, where piston-like displacement is dominating and snap-off is suppressed.…”

“…The porosity is 35%, the permeability is measured to 48 Darcy, and the formation factor is 3. The characteristics of the network are in agreement with sandpacks used by Dong et al (1998) and Meleán et al (2003). They performed imbibition experiments for CA ≈ 0.01-10 (Ca = 10 −8 − 10 −5 ) with strongly water-wet conditions at samples about 100 times longer than the network we consider.…”

We present a dynamic model of immiscible two-phase flow in a network representation of a porous medium. The model is based on the governing equations describing two-phase flow in porous media, and can handle both drainage, imbibition, and steady-state displacement. Dynamic wetting layers in corners of the pore space are incorporated, with focus on modeling resistivity measurements on saturated rocks at different capillary numbers. The flow simulations are performed on a realistic network of a sandpack which is perfectly water-wet. Our numerical results show saturation profiles for imbibition in agreement with experiments. For free spontaneous imbibition we find that the imbibition rate follows the Washburn relation, i.e., the water saturation increases proportionally to the square root of time. We also reproduce rate effects in the resistivity index for drainage and imbibition.

“…In addition, simulation with a continuum model of liquid-vapor phase change [4] and a pore network model of drying [2] have been undertaken. Meanwhile, many other important practical applications, such as building, oil exploitation, functional clothing design, and dam safety analysis [5,6] are closely associated with water migration in porous media and the wetting/drying of porous materials.…”

“…Philippi and Souza [12] employed electron scanning images for obtaining geometrical information of porous materials and therefore numerically describing water migration in cement and lime mortar. A series of X-ray, CT-scanner measurements were conducted to obtain imbibitions' saturation and distributions' tracer saturation profiles at various injection rates of wetting fluid (water) [6]. These investigations show that it is highly possible to employ CT-scan in experimental investigations.…”

A series of experiments were conducted to observe water transport in wood during wetting using a micro-CT combined with scanning, reconstruction, and grey analysis technology. A comprehensive discussion was conducted to explore the characteristics of water transport and moisture distribution caused by local pore structure and properties in the wood sample during wetting. For wetting course of the wood immersed in water, water transport exhibits three stages. At the beginning, the dense region of the wood was wetted and contained some water which was unable to transfer into the sparse region because of the larger capillary force induced by the dense structure. Secondly, as water penetrates the wood, the sparse region contained much more water than the dense region. At this stage, the dense region is unsaturated. Finally, water transfers into both dense and sparse regions and gradually saturates them.
