4 results for “mixing, porous media”
Dataset for "Experimental and Modeling Insights into Mixing-Limited Reactive Transport in Heterogeneous Porous Media: Role of Stagnant Zones"
<p>This dataset contains the observed and simulated BTC of bimolecular transport experiment that was involved in "Yin et al., Experimental and Modeling Insights into Mixing-Limited Reactive Transport in Heterogeneous Porous Media: Role of Stagnant Zones".</p>
A closer look: High-resolution pore-scale simulations of solute transport and mixing through porous media columns
<p>This dataset contains the results of fluid flow (Navier-Stokes) and solute transport (Advection-Diffusion) simulations within columns of granular media generated by virtual gravitational settling of spherical grains. The experiments comprise three media with different degrees of grain-size variability; a range of grain-Peclet numbers is explored. See the homonymous research paper by Sole-Mari et al. (2022, Water Resources Research) for more information.</p> <p>Grains.zip: Positions and radii of the spherical grains for each value of grain-size variability sigma (Matlab's .mat format).</p> <p>ResultsCoarse.zip: Coarse-scale data presented in the aforementioned WRR paper (Matlab's .mat format).</p> <p>Link to the full micro-scale dataset: (soon available)</p> <p>We thankfully acknowledge the computer resources at MareNostrum and the technical support provided by the Barcelona Supercomputing Center (AECT-2019-3-0014).</p> <p> </p>
Mesh and velocity fields for "Resolving Pore-scale Concentration Gradients for Transverse Mixing and Reaction in Porous Media"
<p>This dataset contains the data needed to reproduce the results in the manuscript "Resolving Pore-scale Concentration Gradients for Transverse Mixing and Reaction in Porous Media". The three folders refer to (1) uniform flow, (2) flow through a bead pack, and (3) flow through a Berea sample (from the 11 sandstones repository, Digital Rocks Portal). The meshes and the velocity fields (in the subfolder "velocity") are in a HDF5 format. The meshes and velocity fields can be read using FEniCS version 2019.2.0. The velocity fields need 2nd order Lagrange tetrahedral elements.</p>
Temporal and Spatial Evolution of Pore Scale PDFs of Solute Concentrations to Study Incomplete Mixing in Porous Media
<p>C at M.I for Pe100 (sample): Sample (vector) of pore scale concentrations at Pe100 and five different times.</p> <p>C Chunk for All Pe (sample): Sample (3D block) of pore scale concentrations at the mixing interface for six Peclet number cases ( 10, 32, 100, 316, 1000, 3160) and at 11 different time steps extracted from the full size column. This is extracted using the semi-analytical appraoch to eliminate boundary effect.</p> <p>meanvelocities: Matlab Data of the pore scale longitudinally averaged velocity.</p> <p>MLE: Result of maximum likelihood estimation analysis for 18 different distribution functions (Excel file)</p> <p>SemiAnalytical: Matlab code for the implementation of the semi-analytical apporach.</p> <p>gamma_incomplete: Incomplete Gamma function required for the SemiAnalytical code.</p>
