Diffusion of charged rods across 3D varying section channels
N. Ray, A. Semkiv, J. Harting +1
We analyze the transport of rod-like particles by diffusion and drift in a three-dimensional channel with varying circular or elliptic cross section. Applying the Fick-Jacobs appro…
Parameter estimation for cellular automata
Alexey Kazarnikov, Nadja Ray, Heikki Haario +2
Self-organizing complex systems can be modeled using cellular automaton models. However, the parametrization of these models is crucial and significantly determines the resulting s…
Estimating relative diffusion from 3D micro-CT images using CNNs
Stephan Gärttner, Florian Frank, Fabian Woller +2
In the past several years, convolutional neural networks (CNNs) have proven their capability to predict characteristic quantities in porous media research directly from pore-space…
Local existence of strong solutions to micro-macro models for reactive transport in evolving porous media
Stephan Gärttner, Peter Knabner, Nadja Ray
Two-scale models pose a promising approach in simulating reactive flow and transport in evolving porous media. Classically, homogenized flow and transport equations are solved on t…
Estimating permeability of 3D micro-CT images by physics-informed CNNs based on DNS
Stephan Gärttner, Faruk O. Alpak, Andreas Meier +2
In recent years, convolutional neural networks (CNNs) have experienced an increasing interest in their ability to perform a fast approximation of effective hydrodynamic parameters…
Rigorous Homogenization of a Stokes-Nernst-Planck-Poisson Problem for various Boundary Conditions
Nadja Ray, Adrian Muntean, Peter Knabner
We perform the periodic homogenization (i.e. $\eps\to 0$) of the non-stationary Stokes-Nernst-Planck-Poisson system using two-scale convergence, where $\eps$ is a suitable scale pa…
