Abstract

Characteristics of a complex of heat-mass transfer processes with phase transitions and chemical reaction are numerically investigated at ignition of a thin film of typical liquid condensed substance by single hot metal particles shaped as a hemisphere, disc, and parallelepiped. The influence of a source configuration with a limited energy content on the ignition delay time of liquid is estimated. The ranges of heat source parameters at which the influence of the source configuration on the ignition delay time is minimal are determined.
