They have observed that self-affine aperture fields lead to flow channeling where most of the fluid will travel through several preferential channels (Brown 1987; Tsang and Tsang 1989; Glover et al. 1998; Drazer and Koplik 2000; Méheust and Schmittbuhl 2001, 2003; Auradou et al. 2006).
Under simulated conditions of preferential channels eliminated, average annual TP treatment effectiveness increased by 25%.
Those structures weakened surface rocks and facilitated their erosion, thus forming preferential channels for surface water flows.
For both link creation and information spreading, the interaction network has an important role in determining new connections and preferential channels of item diffusion.
By allowing preferential channels for the gas and liquid phases, counter-current operation is achieved even for millimeter sized catalyst particles without the problem of flooding.
Massive micro fractures (MFs) developed in the ultra-tight formations (such as shale/tight reservoirs), which provide preferential channels for the fluids flow.
The MCC physical properties suggest the conventional fluidized bed as adequate for the granulation process; however, literature reports the occurrence of poor fluidization dynamic (preferential channels and dead zones) during this particle fluidization.
Autonomous behavior is achieved by driving fluid flow through preferential channels based on the fluid's inherent inertial and viscous forces with simplified internal FCD geometry described in Fig. 3.
The spheroid microstructure that is well evidenced in figure 8, and in figures S8, S9, S10, S11, S12, S13, S14, S15, S16, S17, S18, S19, S20, S21 and in Movies S1, S2, S3, shows highly correlated fluctuations that produce, e.g., islets of proliferating cells in the sea of dead cells of the core, and cell and mass flows that follow preferential channels.
