Adiabatic Computation of Internal Blast from Aluminum-Cased Charges in Air

摘要

Calculations have been carried out, using the HP9845A desktop computer, for the maximum overpressures developed by combustion of fuels plus aluminum in confined air volumes. N all, eight fuels were chosen, both conventional and explosive. The mass of fuel to that of metal was varied from 0.1 to 10.0 and the total concentration of fuel plus metal ranged from 0.1 to 10.0 kilograms per cubic meter of incident air. The computations include evaluation of the adiabatic temperatures and of the product compositions, the latter involving the chemical equilibria amongst 28 gaseous and up to five condensed-phase substances.
