Résumé

The blow-off conditions of jet flames of H2/CO2 mixtures in the air cross flow were studied. Two modes of extinction typical for attached and lifted flames were observed. The dependence of ρfuelUjet0U0 on 1/Y1H2, where Y1H2 is hydrogen mass fraction in fuel may be used for the blow-out conditions analysis.
