Porous Media Permeability Models with Grain Roundness and Porosity Data

Jiabin Dong published a collection of datasets on figshare in April 2026 for pore-scale numerical studies. The 706.3 KB collection includes files analyzing the synergistic control of grain roundness and volume on the permeability of fractal porous sandstone. It contains datasets for constructing hierarchical Voronoi porous media, comparing theoretical and actual porosity, and relating roundness to permeability via Lattice Boltzmann Method simulations.

Use Cases

• Constructing hierarchical porous media models based on Voronoi datasets.
• Analyzing the relationship between particle roundness and permeability based on Rw-K datasets.
• Comparing theoretical porosity predictions with actual geometric morphology based on the porosity comparison dataset.
• Evaluating permeability simulation methods based on datasets comparing B-Spline and Vertex substitution results.

Strengths

• Dataset size is 706.3 KB, facilitating quick download and inspection.
• License is CC-BY-4.0, allowing for open sharing and modification.
• Includes velocity field VTI files for visualization in ParaView, supporting result validation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
