Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3970-3983, August 2026.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures
