The aim of this work is to study the kerosene explosibility in closed or vented vessels and to
develop an application to safety systems. The basic characteristics of the model have been
developed for the ignition and the combustion of propulsive powders and adapted to liquid fuels
with appropriate parameters linked to simplified kinetics. A simple representation of the
combustion phenomena based on energy transfers and the action of specific molecular species is
presented. The pressure venting, due to the vent breaking is calculated taking into account the mass
rate of discharge of the different products in the assumption of the standard orifice equations.
The model allows the study of various parameters such as the nature of the kerosene, the fuel ratio
of the mixture, the ignition energy, the thermal exchanges and the influence of the pressure venting
or the vent area. The theoretical results have been compared with data obtained in the course of
experiments performed in small vessel volumes (V0 = 13 and 33 l) and indicate correct preliminary
tendencies.
