Thermal expln applications

Thermal expln theory has many practical and theoretical uses. Two practical applications and several theoretical applications of thermal expln phenomena wiU be considered below An appropriate question to ask is whether thermal expln theory can be applied to designing safe storage of expls. A more direct question can be formulated as how much expl can be safely stored at various ambient temps ... 

The methods of classical kinetics are not applicable to the study of rapid exothermic reactions. On the other hand, exptl measurements of thermal explns (which are relatively simple to obtain) can yield kinetic data for the reactions taking place during the pre-expln induction period, provided that these observations are interpreted correctly, ie, using a sound theoretical basis. Thus, extraction of kinetic data from thermal expln measurements is likely... 

Applications of thermal radiation spectroscopy to expins and pyrots are readily apparent. As a consequence of the highly exothermic nature of explns and flares, significant thermal radiation is emitted which can serve to characterize the reaction processes. The photometric properties of pyrots have been treated in Vol 8, P505-R. In practice, thermal radiation characteristics of explns do not always closely approximate black body properties since the system is non-equilibrium in nature and is time dependent. In addition, some pyrotechnically related materials such as aluminum oxide and magnesium oxide behave as gray bodies with emissivities well below unity. For such systems the radiant emission is reduced as shown in Fig 4...
