Measurement of the laminar burning velocity and kinetics study of the importance of the hydrogen recovery mechanism of ammonia/hydrogen/air premixed flames

Combustion and Flame, 2022
The application of ammonia (NH3) blended with hydrogen (H2) as a fuel in combustion systems is a practical approach to decarbonise the energy sector, and the combustion of the fuel at rich conditions is relevant in emissions control through rich-lean ...

Intrinsic instabilities in premixed hydrogen flames: Parametric variation of pressure, equivalence ratio, and temperature. Part 1 - Dispersion relations in the linear regime

Combustion and Flame, 2022
The impact of intrinsic combustion instabilities is studied for lean premixed hydrogen flames by means of a series of simulations at di ff erent equivalence ratios [0.4-1.0], unburned temperatures [298K-700K], and pressures [1bar-20bar]. In addition to the
