A kinetic model for 2,3,3,3-tetrafluoropropene (HFO-1234yf) high temperature oxidation and combustion is proposed. It is combined with the GRI-Mech-3.0 model, with the previously developed model for 2-bromo-3,3,3-trifluoropropene (2-BTP), and with the NIST C1-C2 hydrofluorocarbon model. The model includes 909 reactions and 101 species. Combustion equilibrium calculations indicate a maximum combustion temperature of 2076 K for an HFO-1234yf volume fraction of 0.083 in air for standard conditions (298 K, 0.101 MPa). Calculations of flame propagation in mixtures of 2,3,3,3-tetrafluoropropene with oxygen enriched air are performed and results are compared with experimental data.
