Combustion of Ammonia, Hydrogen, and Dual-Fuel Mixtures in Engines and Turbines
This research community investigates how ammonia, hydrogen, natural gas, and diesel fuels burn in internal combustion engines and gas turbines, focusing on ignition behavior, flame propagation, and the resulting exhaust emissions.
The work centers on optimizing dual-fuel systems where ammonia or hydrogen is blended with diesel or natural gas to manage ignition and reduce pollutants. Recurring themes include the characterization of premixed flames, the effects of direct injection strategies, and the thermal decomposition of solid propellants like ammonium perchlorate. Researchers employ numerical simulations and experimental testing to analyze how these fuel blends alter combustion efficiency and nitrogen oxide production. The literature consistently links fuel composition to engine performance, with significant attention to the specific challenges of igniting ammonia-hydrogen mixtures and stabilizing flames in gas turbine combustors.
The largest share of this community's output is found in hydrogen research, accounting for 5.1% of all hydrogen-related papers, and 2,328 papers here. It also represents 1.3% of nitrogen research and 1.3% of argon research.
The community comprises 12,887 papers, publishing primarily in Fuel, International Journal of Hydrogen Energy, and Combustion and Flame.
Recent work continues to focus on optimizing hydrogen-ammonia rotary engines, investigating the thermal decomposition of aluminum-lithium alloys, and analyzing the combustion characteristics of sustainable aviation fuels and coal gasification systems.
