... As the permeability of a filter medium depends on fiber orientation (Fotovati et al., 2010b), direct numerical simulation of threedimensional fibrous filter media is the method of choice to study this phenomenon. This methodology was used to study the impact of fiber shape (Fotovati et al., 2011), multilayering fibers with different diameters (Tucny et al., 2020) and the permeability of bidisperse fiber diameter distributions (Clague and Phillips, 1997;Fotovati et al., 2010a;Gervais et al., 2012;Rebai et al., 2011). ...

... A common simplification while investigating the liquid transport in roll-based printing is to treat the roller surfaces as separating plate surfaces. [7][8][9][10][11][12][13][14][15][16][17][18][19] The host plate remains stationary, and the target plate is in vertical, horizontal, or rotational motion. Both plate surfaces may be smooth, representing the liquid transport between two smooth roller surfaces, or one of the plates may contain a cell, representing the liquid flow out of a cell on an ink-metering roller. ...

... We explore the universal rheological properties of interconnected periodic networks, independently of the molecular details of the constituents. We use a coordinate transformation introduced by Drolet, Chen, and Viñals, 13) which makes it possible to evaluate stress-strain relations by solving a set of the amplitude equations for the mesoscopic structures. We employ a mode expansion method and numerically solve the 18 amplitude equations describing a gyroid. ...

... The nip pressures adapted in the simulation correspond to a flat plat that moves vertically to (positive pressure) or away from (negative pressure) the paper substrate. The numerical simulation was followed up and further improved by Holmvall et al (2011), who introduced the immersed and moving boundary method into the simulation. The objective of this work is to extend the application of the Bosanquet model to a printing situation, where an arbitrary and time-dependent nip-pressure presents. ...

... Dubé and co-workers studied the hydrodynamic flow of a half-tone dot pressed onto a model porous substrate by a nip that moved vertically either close to or away from the substrate surface [8]. Ink movement under this nip pressure was described by the lubrication approximation of the Navier-Stokes equations taking into account of fluid tack. ...

... In the case of the printing process, proper interaction of the paper structure with liquids is particularly important. To obtain a high-quality print, it is required that the liquid must be precisely and evenly absorbed within a limited, strictly controlled range [4,5,14,22,43,45]. In paper technology, the operation to reduce the susceptibility of the paper to liquid penetration is known as paper sizing. ...

... Compared with plastics, steel, cement, and other structural material, wood has unique mesoporous and hierarchical structure stemming in its biological origin, which makes it inherit wood material characteristics such as high ratio of strength to weight, certain viscoelasticity, and anisotropy. The mesoporous structures that consist of pores in hardwood, lumina varying in diameter from 10 to 80 μm, pits, and gum canal or resin canal, which together form the interpenetrating cannular networks and offers the penetrability, accessibility, and reactivity of wood materials [1][2][3]. In the past few decades, bio-inspired intelligent responsive materials have become one of the most exciting fields in the research of new materials. ...

... The greatest feature of phage display is the unification of genotype and phenotype. At the same time, because of its simple operation, effective and easy to control, it is currently widely used in epitope analysis [53,54], molecular interaction [55], and preparation of monoclonal antibodies. [56], drug screening [57], vaccine development [58], disease pathogenesis [59] and functional genomics [60] and other research fields. ...

... These CFD methods can also be used to retrieve other fields such as the temperature across the filter wall (Yamamoto and Nakamura, 2011). Once the flow field has been computed, filter capture efficiency can also be obtained by tracking individual particle trajectories using Lagrangian approaches (Wiegmann et al., 2006;Vadeiko and Drolet, 2009;Becker et al., 2016;Stewart et al., 2004) or solving mass transport equations using the Eulerian approach and using probabilistic models of soot deposition (Yamamoto and Ohori, 2012;Tsushima et al., 2010). Physical phenomena at the micron scale can thus be studied using this multi-step methodology. ...
