Technical case studies
Rectangular-Slot Liquid–Gas Jet in OpenFOAM
A phase-aware OpenFOAM account of rectangular-slot interface deformation, flow diagnostics, and connected morphology.
Open project record- Question
- How does a rectangular-slot liquid–gas interface deform under aerodynamic forcing across an early-time VOF window?
- Method
- OpenFOAM v2406 interFoam; laminar two-phase VOF; CPU/MPI.
- Main output
- Twenty-five native states connect phase-aware fields to a largest-component morphology result.
- Relationships
- Source case for the VisualOpenFOAM workflow and the legacy OpenFOAM KH proxy route.
- Limitations
- Early-time laminar simulation; it does not resolve atomization, production CFD, or experimental agreement.
VisualOpenFOAM
A Linux-first CLI for reproducible OpenFOAM and VTK scenes and field reports.
View project- Question
- How can an OpenFOAM visualization session become an inspectable, repeatable scientific workflow?
- Method
- OpenFOAM/VTK inventory, Linux CLI plans, headless Blender, and field-report outputs.
- Main output
- Versioned case, field, scene, gallery, and report plans with scientific semantics attached.
- Relationships
- Developed alongside the separate rectangular-slot OpenFOAM study and related methodologically to VisualBasilisk.
- Limitations
- Real OpenFOAM and VTK readers are the next development focus.
Basilisk jet benchmark visualization
A two-phase VOF benchmark comparing an official circular route with a secondary rectangular top-hat imposed inlet.
Open project record- Question
- Which interface and scalar comparisons remain interpretable across the circular and rectangular benchmark routes?
- Method
- Basilisk two-phase VOF outputs and source-grounded visualization.
- Main output
- Curated interface, speed, vorticity, and ambient-context panels with pressure excluded.
- Relationships
- Provides the scientific case context for the separate VisualBasilisk bridge.
- Limitations
- Benchmark visualization only; the rectangular inlet is top-hat, pressure output is unavailable, and the case is not fit-ready.
VisualBasilisk
Source-first Basilisk VOF/facet-to-Blender bridge with explicit manifests, dry-run render plans, tiny synthetic fixtures, and clear scientific scope.
Open project record- Question
- How can Basilisk facet exports enter a reproducible visualization workflow without bundling solver data?
- Method
- Python CLI, explicit facet/frame manifests, dry-run Blender plans, metadata reports, and tiny synthetic fixtures.
- Main output
- Checked manifests, render plans, contact sheets, and metadata reports for small, explicit inputs.
- Relationships
- Companion bridge to the Basilisk benchmark page and a separate implementation from VisualOpenFOAM.
- Limitations
- Bridge utility rather than a solver or full renderer; real Basilisk fixtures and scientific validation are outside the public snapshot.
ideal-momentum-jet-explorer
Interactive scientific-computing demonstration for jet-model exploration, explanatory visualization, and technical communication.
Open project record- Question
- How do nozzle geometry and prescribed area growth affect the normalized state of an ideal momentum jet?
- Method
- React/TypeScript static application implementing a prescribed-area-growth reduced-order jet model.
- Main output
- Interactive plots and geometry, shareable model states, CSV/configuration exports, and browser-side reports.
- Relationships
- Explainer for the reduced model; accepts clearly labeled external comparison overlays without converting them into validation.
- Limitations
- Exploratory reduced-order model with synthetic overlays; not predictive engineering design software.
SPH simulation and visualization
A case-study family connecting GPU SPH outputs to reviewable scientific media and a rectangular-jet geometry-proxy handoff.
Open project record- Question
- How can particle-simulation output be turned into interpretable media while preserving model and post-processing context?
- Method
- DualSPHysics outputs, VTK/IsoSurface post-processing, Blender rendering, and video assembly.
- Main output
- Hosted visual sequences plus a geometry-metrics handoff to reduced-model analysis tools.
- Relationships
- The rectangular proxy connects to SprayGeo and ideal-momentum-jet-explorer analysis paths.
- Limitations
- Visualization and post-processing evidence; the rectangular case is a single-phase proxy, not breakup or experimental validation.
