Supplementary Files for a High-Pressure Hydrogen Combustor DNS Simulation

Supplementary files for the article "Direct numerical simulation of a high-pressure hydrogen micromix combustor: flame structure and stabilisation mechanism". The dataset consists of MP4 video files totaling 35.3 MB, authored by Thomas Howarth and last updated on 2026-04-24. The underlying research uses direct numerical simulation with detailed chemistry to examine flame zones and stabilization mechanisms in a hydrogen combustor.

Use Cases

• Visualizing flame structure and ignition events based on the described simulation results
• Analyzing turbulent mixing and flame stabilization mechanisms in high-pressure hydrogen combustion
• Studying the behavior of core and peripheral flame zones mentioned in the description
• Validating computational models for lean, inhomogeneously-premixed lifted jet flames

Strengths

• Dataset is associated with a peer-reviewed scientific article describing a direct numerical simulation with detailed chemistry.
• The supplementary files are provided under a permissive CC BY 4.0 license.
• The description provides a detailed technical summary of the simulation methodology and key findings, such as the core flame consuming over 85% of the fuel.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 35.3 MB size suggests it is a small collection of supplementary media files, not the primary simulation data.
