This study presents a combined numerical and action research of burning aspects, nitrogen oxide formation in a micro-flame front device heat generator operating under high excess air conditions. The analysis covers a wide range of air excess ratios (α = 4.4–10), representative of practical heating system regimes. Numer...
In conventional aero-engine testing, the combustor and afterburner are usually evaluated separately, which increases cost and energy consumption because two high-temperature sources are required. This study proposes a flange-type mixer for integrated testing, in which ambient air is transversely injected to cool the...
Under the CONVERGE software platform, different combustion models and soot models were coupled to numerically simulate the turbulent combustion process and soot formation characteristics of n-dodecane. The predicted combustion characteristics and soot formation characteristics were compared and analyzed against experim...
This study employs numerical simulations to systematically investigate the combustion characteristics of methane/ethanol blended fuel–air mixtures under non-premixed turbulent conditions. The effects of the methane blending ratio on the flow-field structure, flame morphology, NO emissions, and combustion efficiency are...
The global shift toward cleaner energy has positioned hydrogen-enriched methane (CH4/H2) as a practical bridge fuel. While it burns more efficiently and produces fewer carbon emissions than traditional hydrocarbons, it introduces operational and safety challenges. Hydrogen’s high reactivity and rapid burning velocity i...
Abstract To clarify the low-temperature ignition characteristics of a gas-turbine can-annular combustor, a coupled numerical model of a torch igniter and combustor was established to examine ignition limits, torch-jet behavior, internal flow, fuel-droplet evaporation, and transient flame propagation. With an ignition e...
