Due to their high global warming potential (GWP), hydrofluorocarbon refrigerants (HFCs) are systematically being phased out. Replacements with low GWP exist, but give rise to safety hazards as they are found to be mildly flammable. The assessment of the

The burning velocity of mixtures of the refrigerant R-32 (CH2F2) with air over a range of equivalence ratios are studied via spherically expanding flames SEFs in a large, optically accessible spherical chamber at constant pressure. Shadowgraph images from

A mechanism for the combustion of the refrigerant R-32 (CH2F2) in air mixtures was developed and validated through comparisons with measured flame speeds for a range of equivalence ratios (0.9 to 1.4) and pressures (1 to 3 bar) using a constant-volume
