Verification of Particle-Laden Flow Simulations in a Vertical Channel

Michael C. Baker from Iowa State University simulated particle-laden flows in a vertical channel using Eulerian–Eulerian and Eulerian–Lagrangian models. The dataset contains primary and turbulent statistics extracted from these simulations for cases with varying mass loading and particle Stokes numbers. Results compare the performance of the two modeling approaches for capturing flow transitions.

Use Cases

• Verify Eulerian–Eulerian model performance against Lagrangian benchmarks based on the described comparative statistics.
• Study the transition from shear-induced to cluster-induced turbulence based on the described flow behavior.
• Analyze the impact of particle Stokes number and mass loading on simulation accuracy as detailed in the description.
• Benchmark anisotropic-Gaussian closure models for particle-phase Eulerian simulations using the provided case results.

Strengths

• Dataset is derived from controlled computational simulations, allowing for precise comparison of model performance.
• Analysis includes two distinct particle regimes (large and small Stokes numbers) and varying mass loadings, providing multiple test cases.
• Results are directly compared between two established modeling frameworks (Eulerian–Eulerian and Eulerian–Lagrangian).

Limitations

• Description metadata is limited; actual data quality, format, and structure require manual inspection after download.
• Row count and column-level documentation are absent; field semantics must be inferred.
• Data may reflect the specific bias of synthetic simulations from the paperswithcode platform, limiting generalizability to real-world flows.
