Ignition

Abstract

Chemical chain and thermal ignition phenomena are described. The thermal theories of Semenov and Frank-Kamenetskii are developed for analysis of the criteria for spontaneous ignition. Forced ignition by sparks and the concept of minimum ignition energy are presented as well as ignition by adiabatic compression and shock waves. Other specialized ignition processes, such as hypergolicity, pyrophoricity, and catalytically assisted ignition, are introduced.
