We study mixing-controlled chemical reactions in unsaturated porous media from a pore-scale perspective. The spatial heterogeneity induced by the presence of two immiscible phases, here water and air, in the pore space generates complex flo...
Electrical Signatures of Diffusion-Limited Mixing: Insights from a Milli-fluidic Tracer Experiment [0.03%]

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%]
弹性变形穿孔介质中传运过程的多尺度建模与模拟

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...
