Multi-stage oxidation of a CH2F2/air mixture examined by weak flames in a micro flow reactor with a controlled temperature profile

Oxidation of CH2F2 (R32), a widely used refrigerant, was investigated experimentally and computationally using a micro flow reactor with a controlled temperature profile (MFR). Specifically, we examined weak flames of a stoichiometric CH2F2/air mixture in MFR observed at low flow velocities. In the case of the maximum wall temperature of 1300 K, weak flames showed two luminous regions at 1240 and 1290 K, implying two-stage oxidation....
