Description of  Propellants and Explosives: Thermochemistry and Combustion

The combustion phenomena of propellants and explosives are dependent on physicochemical parameters such as ingredients, catalysts, pressure, initial temperature, and flow field. This book presents the fundamental bases of energetics of materials, deflagration and detonation, thermochemical process of decomposition and combustion, and combustion wave structures. The combustion mechanisms of various types of energetic materials, propellants, and explosives are discussed based on the heat transfer process in the combustion waves. The burning rate models are also presented to understand the rate-controlling steps of combustion processes, which show the relationships of burning rate versus pressure and initial temperature. The combustion processes of propellants and explosives are highly complicated because of the heterogeneous structures of the materials, and because of phase changes from solid to liquid, and to gas under high pressure and temperature conditions. Therefore the real combustion phenomena are demonstrated by the use of a number of colored photographs during burning. New applications of energetic materials such as pyrolants and ducted rockets for an advanced propulsion system are also described.
