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

open access: yesInternational 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

Improved combustion stability of biogas at different CO2 concentrations using inhomogeneous partially premixed stratified flames

open access: yesGlobal Energy Interconnection
Biogas is a renewable and clean energy source that plays an important role in the current environment of low- carbon transition. If high-content CO2 in biogas can be separated, transformed, and utilized, it not only realizes high-value utilization of ...

Simulation of partially premixed turbulent flames

open access: yes, 2017
This work numerically investigates the turbulent partially premixed flames, which are ubiquitous in combustion powered devices. This combustion mode involves many physical complexities such as flame propagation in unevenly premixed mixture of fuel and oxidiser, turbulence/flame interaction in presence of mixture fraction gradients, triple flame ...

Numerical investigation on combustion performances of premixed H2-air jet flames above a sudden expansion micro-nozzle

open access: yesCase Studies in Thermal Engineering
Our previous study demonstrated that divergent micro-nozzles designed for H2-fueled domestic gas stoves can achieve a higher flame temperature than conventional straight micro-nozzles, but are more susceptible to flashback. To address this safety concern,
