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.
