Molecular diffusion in liquids is a key process in numerous systems: it is often the reaction rate limiting factor in biological or chemical reaction. Molecular diffusion has been recognized as the ultimate mechanism by which substances con...
Multi-Scale Modeling and Simulation of Transport Processes in an Elastically Deformable Perforated Medium [0.03%]

Jonas Knoch et al.
In this paper, we derive an effective model for transport processes in periodically perforated elastic media, taking into account, e.g., cyclic elastic deformations as they occur in lung tissue due to respiratory movement. The underlying mi...
Ferrofluid Impregnation Efficiency and Its Spatial Variability in Natural and Synthetic Porous Media: Implications for Magnetic Pore Fabric Studies [0.03%]

Magnetic pore fabrics (MPF) are an efficient way to characterize pore space anisotropy, i.e., the average pore shape and orientation. They are determined by impregnating rocks with ferrofluid and then measuring their magnetic anisotropy. Ob...
Relating Darcy-Scale Chemical Reaction Order to Pore-Scale Spatial Heterogeneity [0.03%]
达西尺度化学反应阶数与孔隙尺度空间异质性之间的关系

Po-Wei Huang et al.
Due to spatial scaling effects, there is a discrepancy in mineral dissolution rates measured at different spatial scales. Many reasons for this spatial scaling effect can be given. We investigate one such reason, i.e., how pore-scale spatia...
Effect of dynamic contact angle variation on spontaneous imbibition in porous materials [0.03%]

We investigate the influence of contact angle variations on spontaneous imbibition of moisture in porous materials. While the contact angle is typically assumed constant when modelling the moisture transfer in porous media, experimental fin...
Lattice Boltzmann Modeling of Drying of Porous Media Considering Contact Angle Hysteresis [0.03%]
考虑接触角迟滞的多孔介质干燥的格子Boltzmann模拟
Feifei Qin,Jianlin Zhao,Qinjun Kang et al.
Feifei Qin et al.
Drying of porous media is governed by a combination of evaporation and movement of the liquid phase within the porous structure. Contact angle hysteresis induced by surface roughness is shown to influence multi-phase flows, such as contact ...

I use a mechanical model of a soft body to study the dynamics of an individual fluid droplet in a random, non-wettable porous medium. The model of droplet relies on the spring-mass system with pressure. I run hundreds of independent simulat...
Pore-Scale Transport and Two-Phase Fluid Structures in Fibrous Porous Layers: Application to Fuel Cells and Beyond [0.03%]

Meisam Farzaneh et al.
We present pore-scale simulations of two-phase flows in a reconstructed fibrous porous layer. The three-dimensional microstructure of the material, a fuel cell gas diffusion layer, is acquired via X-ray computed tomography and used as input...
