Abstract:

A Fortran IV computer code is described which computes the equilibrium or mixed frozenequilibrium thermodynamic state of general chemical systems. Closed fixed mass molecular compositions are evaluated from relative elemental quantities, species thermochemical data and two state properties pressure and temperature or enthalpy. Open system diffusive mass flux dependent states are defined from surface equilibrium considerations utilizing a film coefficient model which accounts for the unequal diffusion of species. The generality of the formulation allows computations for a broad range of environments and surface materials including charring ablators. This computer code is designated Version 3 of the Aerotherm Equilibrium Surface Thermochemistry code EST3 and provides surface mass balance quantities needed for ablation predictions by the Aerotherm Charring Material Ablation code CMA.
