Flame sheet starting estimates for counterflow diffusion flame problems
Journal of Computational Physics, 1987 The authors develop a flame sheet starting procedure for the numerical modelling of laminar counterflow diffusion flame problems. The model couples the equations of mass and tangential momentum with a Shvab- Zeldovich equation to provide estimates for the mass flux in the transverse direction, the similarity function, the temperature and the stable ...

Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner
Journal of Thermal Science and Technology, 2018 Oxygen combustion of CH4-CO2 mixture in a small-scale counterflow burner was studied. A diffusion flame was stabilized in the gap between opposed ports ejecting fuel and oxygen gases, and its thickness which depended on the gap distance between burner ...

Counterflow flame extinction of ammonia and its blends with hydrogen and C1-C3 hydrocarbons
Applications in Energy and Combustion Science, 2022 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.
