Alternative Derivation of the Equations Governing the Fireball Thermo Dynamics

Abstract

Two alternate derivations of the equations governing the thermodynamics for a simple model of fireball rise and entrainment are presented. These two derivations place emphasis on different sets of thermodynamic variables. This report indicates that it is important to consider the time rate of change of the specific heat ratio, in the equations governing the fireball thermodynamics in the cases where: (1) energy storage in internal degrees of freedom is significant and (2) where energy transfer via dissociation and association processes is significant.
