Explosion Characteristics of a Volatile Explosive

Abstract

Thermal explosion of volatile energetic materials has been investigated based upon the thermal explosion theory of a gaseous mixture. The critical and transition condition expressions for the thermal explosion of these materials are obtained. The analytical solutions not only deal with the steady-state solution but also cover the unsteady state solution. The different cases and different parameters which affect the critical conditions are investigated in details. Also the numerical solution of the energy equation is offered to give the different families of temperature - time histories. The relation between the critical parameters as ignition timing, ignition temperature, Semenov number and others with different boundary conditions is offered. In this work, the critical and transition conditions of the explosion of the volatile energetic materials through the analytical solution to the problem was introduced. The numerical solution of the unsteady state equation to the problem was offered. The relation between the critical parameters was also presented. The effect of evaporation of the volatile materials as compared with the non-volatile materials on the critical conditions was shown.
