AEROTHERM CHEMICAL EQUILIBRIUM (ACE) COMPUTER PROGRAM
The Problem: Notes: 
Thermochemical analysis of chemicals in equilibrium. 1. This program is written in FORTRAN IV for use on an 
IBM-7094 computer. 
The Solution: 2. Inquiries concerning this program should be directed 
The Aerotherm Chemical Equilibrium (ACE) computer to: 
program is an extremely versatile code for calculating COSMIC 
quantities of importance to a broad variety of thermo- Computer Center 
chemical processes. Information Services

How It's Done: University of Georgia 
The thermochemical processes treated may be divided Athens, Georgia 30601 
into two categories: closed systems and open systems. Reference: LEW-11722 
Closed systems are those for which the relative amounts •	
of each chemical element in the system are prespecified. Source: C.A. Powars and R.M. Kendall 
Open systems are those for which the relative amounts of Aerotherm Corporation 
chemical elements depend on various mass transfer rates, under contract to 
due for example, to boundary layer convection or solid Lewis Research Center 
surface degradation. The ACE program can treat both (LEW.l 1722) 
systems in chemical equilibrium and systems for which 
certain reactions are kinetically controlled.
