X-ray Computed Tomography images show the three-dimensional temporal mixing of methanol-ethylene-glycol and brine solutions in a random bead pack. The dataset captures the spatial and temporal evolution of solute plumes at a resolution of about (2x2x2) mm³ across Rayleigh numbers (Ra) from 2000 to 5000. The British Geological Survey produced this dataset, which was last updated on 2026-04 09.
Use Cases
- Modeling convective mixing processes based on the observed three-stage evolution from diffusion to convection to shutdown.
- Estimating non-dimensional convective mass flux based on the derived Sherwood number relationship (Sh = 0.025Ra).
- Comparing experimental convective mixing against numerical diffusive scenarios based on the computed macroscopic quantities like dissolution rates.
- Visualizing flow patterns in porous media based on the three-dimensional temporal imaging of solute plumes.
Strengths
- Provides three-dimensional temporal imaging at a spatial resolution of about (2x2x2) mm³.
- Experiments cover a defined regime of Rayleigh numbers from 2000 to 5000.
- Includes analysis of macroscopic quantities like dissolution rates and horizontally averaged concentration profiles.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
