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.
