Abstract:

The 18th in a series of mathematical investigations of the thermodynamics of ablative materials, the study considers aluminum over a range of temperatures up to 6000 deg K and pressures up to 1000 atmospheres. Two sets of equilibrium equations are used--one representing a pure gas phase, the other a heterogeneous system of gas and condensed solid or liquid aluminum. The gas phase of the heterogeneous chemical system, like the homogeneous gas phase, comprises 3 gaseous species. Computational results are presented in both tabular and graphic form. The latter comprises a a conventional Mollier diagram in which specific enthalpy is plotted against specific entropy, with cross plots of temperature, pressure, and molecular weight of moles of condensed aluminum b a plot of volume versus temperature for aluminum and c a plot of vaporization temperature for aluminum and graphite at various pressures.
