Laminar Burning Velocities of Methanol/Ammonia/N-Heptane Fuel Blends

A dataset containing laminar burning velocities for ternary fuel blends of methanol, ammonia, and n-heptane. It includes measured velocities for blends like M20A80, M40A60, M60A40, and M80A20, with results showing increases up to 50% when adding n-heptane. The data was contributed by Yihang Huang and published on figshare in May 2026.

Use Cases

• Validate chemical kinetic mechanisms for methanol/ammonia/n-heptane blends based on measured burning velocities.
• Analyze the effect of n-heptane substitution ratio on flame propagation speed under different equivalence ratios.
• Study the shift in dominant sensitivity contributions from reactions involving CH2OH, HCO, and NH3 as equivalence ratio changes.
• Model the enhancement of H/O radical chain-branching and radical circulation in ternary fuel combustion.

Strengths

• Includes specific percentage increases in laminar burning velocities (e.g., 50%, 31.97%, 22.54%, 4.68%) for different fuel blends.
• Describes a validated detailed chemical kinetic mechanism for the ternary fuel system.
• Provides results for multiple fuel compositions (M20A80, M40A60, M60A40, M80A20) and equivalence ratios (0.8 to 1.2).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 29.7 KB, indicating a very limited scope and likely small sample size.
