Counterflow flame extinction of ammonia and its blends with hydrogen and C1-C3 hydrocarbons
Ammonia as a fuel offers the potential to avoid carbon emissions, but its combustion is hindered by low reactivity. Here, the extinction limits of NH3 and NH3 plus reactivity enhancers were measured in the counterflow laminar non-premixed flames.

Propagation Properties of Turbulent Premixed Flames Neutral for Thermo-Diffusive Effects
Burning velocity is one of the important properties of premixed turbulent flames. Premixed turbulent flames are, in general, subjected to the thermo-diffusive effects in addition to the increase in the flame front area due to the influence of turbulence.
