On the scale of “simultaneous” influence of several “hot” particles on the conditions of heat and mass transfer at ignition of liquid condensed substance

Abstract

Processes of heat and mass transfer at igniting a film of a typical liquid burning substance—kerosene—by several small-size hot particles are investigated numerically. Characteristics of ignition by several particles are compared with similar parameters in a system of single hot particle-liquid fuel film-air. It is found out that a value of the interparticle distance affects characteristics of the process. Three possible regimes of ignition in a system of two hot particles-liquid fuel film-air, depending on the distance between the heat sources, are revealed.
