Projects

Technical case studies and applied research begin with stakeholder problem discovery, then connect physical assumptions to methods, contributions, results, and interpretable technical decisions.

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.

View project

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 earlier OpenFOAM KH proxy route.
Scientific context: This study documents early-time laminar VOF interface dynamics across 25 native states.

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.
Scientific context: Demonstrated with explicit case and field contracts, deterministic plans, and synthetic reference fixtures.

Basilisk jet benchmark visualization

A two-phase VOF benchmark comparing the primary circular benchmark sequence with a secondary rectangular top-hat imposed inlet.

View project

Question: Which interface and scalar comparisons remain interpretable across the circular and rectangular benchmark routes?
Method: Basilisk two-phase VOF outputs and published-case visualization.
Main output: Curated interface, phase, speed, vorticity, and ambient-context panels.
Relationships: Provides the scientific case context for the separate VisualBasilisk bridge.
Scientific context: The figure set centers on interface, phase, speed, and vorticity fields with informative exported variation.

VisualBasilisk

A reproducible Basilisk facet-to-Blender bridge for checked manifests, render plans, and traceable visualization metadata.

View project

Question: How can compact Basilisk facet exports enter a reproducible visualization workflow through explicit inputs?
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.
Scientific context: Validated workflow: explicit facet manifests, deterministic render plans, contact sheets, and traceable metadata reports.

Ideal Momentum Jet Explorer

Interactive scientific-computing demonstration for jet-model exploration, explanatory visualization, and technical communication.

View project

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: The overlay interface preserves the source identity of external comparison curves.
Scientific context: Area growth and spreading angles are explicit model inputs; imported overlays retain their source identity for transparent comparison.

SPH simulation and visualization

A case-study family connecting GPU SPH outputs to reviewable scientific media and a rectangular-jet geometry-proxy handoff.

View project

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.
Scientific context: The rectangular sequence is a single-phase geometry proxy used for visualization and geometry-metric extraction.
