Frank expls

By incorporating small amounts of impurities in expls, such as LA, the thermal parameters of the Frank-Kamenetskii equation hardly change, but the induction periods notably change...

A thermal explosion theory as developed by D.A. Frank-Kamenetskil (Ref 5) led to the equation AT = -[Pg.565]

Kinetic data, whether they are obtained classically from isothermal decompn studies or by DSC, can be used to calculate the critical temp at which any size of an expl can self-heat to expln. The heat-balance problem has been examined by Frank-Kamenetskii (Ref 1) and by Zinn and Mader (Ref 4). The resulting relationship between kinetic and geometric factors is as follows. ... 

Steady-state Condition dTjdt=0, and the Concept of Critical Temperature and Size Frank-Kamenetskii (Refs 1 4) and Chambre (Ref 2) examined the possible steady-state solutions to Eq 7 for 9 0/9t=O, and symmetrical heating of potentially expl materials, with boundary conditions of ...
