Thermal Explosion with Variable Thermal Conductivity: Criticality and Its Disappearance

摘要

Thermal stability of reacting masses, whose thermal conductivity is a function of temperature, is investigated. Some general results relating to criticality and its disappearance are presented. A particular study is made of the disappearance of criticality for the slab geometry with infinite Biot number (Frank-Kamenetskii conditions) for both linear and exponential forms for the temperature dependence of conductivity.
