Sustainable Dual‐Fuel Combustion of NH3/CH4: Role of Equivalence Ratio Pairing in Flame Dynamics and Emissions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Ammonia (NH3)/methane (CH4) dual‐flame combustion offers a promising strategy to enhance NH3 utilization while mitigating NOx emissions. However, the effects of individual flame equivalence ratios on flame behavior and pollutant formation remain inadequately understood, particularly under stoichiometric and rich CH4 conditions.

Hydrogen‐Enriched Direct Injection Diesel Engine Performance, Emission, Combustion, and Sensitivity Analysis Using Ethanol–Nahar Biodiesel Blends

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Energy is essential for performing work and vital for advancing and evolving humanity. However, conventional energy sources are nonrenewable, have finite reserves, and are geographically restricted. Therefore, it is imperative to explore alternative energy sources that are renewable, locally accessible, and produce fewer emissions.

Balancing Accuracy and Runtime in Energy and Pollutant Predictions for CH4/H2 Furnaces: A CFD Study on Chemical Mechanisms for MILD Combustion

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
In moderate or intense low‐oxygen dilution (MILD) furnaces, there is a challenge in using an accurate mechanism in the computational fluid dynamics (CFDs) simulation with minimum computational runtime, as with the application for most furnaces; thus, it needs to identify the most efficient mechanisms.

Influence of high ethane content on natural gas ignition

Revista Ingenio, 2019
The effect of ethane on combustion and natural gas autoignition was studied in the present paper. Two fuel mixture of natural gas with high ethane content were considered, 75% CH4 – 25% C2H6 (mixture 1), and 50% CH4 – 50% C2H6 (mixture 2).
