Abstract

The combustion initiation of condensed mixture with unlimited mass by limited high-temperature spot was mathematically modelled. It was shown that in contrast to the sample critical diameter, at which the combustion dies out due to heat loss, the critical radius of the hot spot upon initiation of large-volume gas-free mixture is determined only by its physicochemical characteristics (Zel’dovich number).
