Predicting Flow in Firebrand Pile using Pore Network Model
… more accurate in the porosity range of interest. Pore network models were developed for the simulation of flow profiles utilizing the permeability data collected. The non-uniform network, which better represents a randomly stack firebrand pile, resulted in a more complex multidimensional flow …

Machine Learning Methods and Computationally Efficient Techniques in Digital Rock Analysis
… Super Resolution Convolutional Neural Networks (SRCNNs) and Enhanced Deep Generative Adversarial Networks (EDSRGANs) are shown in 2D and 3D to compensate for resolution-FOV limitations. SRCNNs boost resolution and recover edge sharpness, while EDSRGANs also recover texture. The noise …

Modeling single-phase flow and solute transport across scales
… accurately propagate information across scales. Pore-scale modeling (coupled with experiments) has assumed an important role in improving our fundamental understanding at the small scale, and is frequently used to inform/guide modeling efforts at larger scales. Among the various methods, there …

Nonequilibrium Phenomena in Multiphase Flow, Transport, and Phase Change in Porous Media: Pore-Level Physics, Network Modeling, and Upscaling
… modeling approaches across scales---from pore-scale (e.g., nanometer to millimeter), to representative-elementary-volume (REV)-scale (e.g., centimeter to meter), to field-scale (e.g., meter to kilometer). To date, most field-scale models are built upon the thermodynamic equilibrium …

Multiphysics Transport in Heterogeneous Media: from Pore-Scale Modeling to Deep Learning
… shale formations are investigated at the single-pore scale using molecular dynamics simulations. In the single-component gas recovery, a super-diffusive scaling law was found for the gas production due to the strong gas adsorption-desorption effects. For binary gas (methane/ethane) mixtures, …
