Visual Analysis of Displacement Processes in Porous Media using Spatio-Temporal Flow Graphs
Alexander Straub, Nikolaos Karadimitriou, Guido Reina +3
We developed a new approach comprised of different visualizations for the comparative spatio-temporal analysis of displacement processes in porous media. We aim to analyze and comp…
Visualizing particle networks in granular media by in situ X-ray computed tomography
Matthias Ruf, Kianoosh Taghizadeh, Holger Steeb
In this contribution, cylindrical samples consisting of monodisperse soft (rubber) and stiff (glass) particles are pre-stressed under uniaxial compression. Acoustic P-waves at ultr…
Visual Analysis of Two-Phase Flow Displacement Processes in Porous Media
Steffen Frey, Stefan Scheller, Nikolaos Karadimitriou +4
We present the visual analysis of our novel parameter study of porous media experiments, focusing on gaining a better understanding of drainage processes on the micro-scale. We ana…
Investigations into the opening of fractures during hydraulic testing using a hybrid-dimensional flow formulation
Patrick Schmidt, Holger Steeb, Jörg Renner
We applied a hybrid-dimensional flow model to pressure transients recorded during pumping experiments conducted at the Reiche Zeche underground research laboratory to study the nor…
Simulation of flow in deformable fractures using a quasi-Newton based partitioned coupling approach
Patrick Schmidt, Alexander Jaust, Holger Steeb +1
We introduce a partitioned coupling approach for iterative coupling of flow processes in deformable fractures embedded in a poro-elastic medium that is enhanced by interface quasi-…
Detecting micro fractures: A comprehensive comparison of conventional and machine-learning based segmentation methods
Dongwon Lee, Nikolaos Karadimitriou, Matthias Ruf +1
Studying porous rock materials with X-Ray Computed Tomography (XRCT) has been established as a standard procedure for the non-destructive visualization of flow and transport in opa…
Comparative study on mesh-based and mesh-less coupled CFD-DEM methods to model particle-laden flow
D. Markauskas, H. Kruggel-Emden, R. Sivanesapillai +1
A comparative study on mesh-based and mesh-less Computational Fluid Dynamics (CFD) approaches coupled with the Discrete Element Method (DEM) is presented. As the mesh-based CFD app…
