Chemical Equilibrium of Complex Mixtures — CEA

CEA requires two types of data that are common to all problems thermodynamic data and thermal transport property data. These two data sets include approximately 1340 gaseous and condensed species as reaction products and thermal transport property data for 155 gaseous species. The data sets may be extended or edited by the user. 

Problem input consists of seven categories of input datasets in a general freeform format. A simple rule for defining the reactant composition is as follows  

two fuel components are defined — methane and benzene — with their weight percent and the temperature in Kelvin. The oxidant is liquid air at 88 K and has an enthalpy of 55 Joule per mole. 

The problem to be solved is defined according to different problem areas, such as temperature and pressure problems, entropy and volume problems, rocket or shock problems, or detonation problems. A simple problem can be defined as follows  

The program produces different output including tables of thermodynamic and equilibrium data and information about the iteration procedures. The report provides particular information on rocket performance, detonation, and shock parameters that helps to decide the appropriate rocket design in the engineering process.
