A numerical analysis of the scale of influence of the mixed convection of an oxidant and a fuel vapor on the characteristics of the gas-phase ignition of the film of a typical liquid condensed substance - kerosene - by a small-size metal particle heated to high temperatures has been made. The limiting values of the velocity of air-mass motion for which no ignition conditions are realized in the system "metal particle heated to high temperatures-kerosene films-air" have been established. The ranges of variation in the air temperature and the initial warmed-up-particle temperature in which the ignition conditions are realized have been determined. It has been shown that no ignition occurs even for a high heat content of the heating source when Re > 1.3•103.
