Rocket operation is modeled by a combustion (hp) process, followed by an isentropic expansion through the rocket nozzle. CEA determines performance based either on a continuous equilibrium adjustment during the expansion or on a composition 'frozen' at user-chosen point. CEA determines and lists the rocket thrust, c*, Isp, Ivac and other important ...

Data subsets for use in CEA, SUBEQ or any other computer program.
17 apr 2023 · CEA is a FORTRAN program that calculates chemical equilibrium compositions and properties of complex mixtures for various applications, such as rocket performance, detonations, and shock waves. It uses thermodynamic and transport data for over 2000 species and is widely used by the aerodynamics and thermodynamics community.
20 dic 2023 · The NASA Glenn thermodynamic database was developed for use with computer programs that require standard state thermodynamic properties of individual species. NASA Glenn’s computer code CEA (Chemical Equilibrium with Applications) uses these data, documented in:
The CEA program calculates chemical equilibrium product concentrations from any set of reactants and determines thermodynamic and transport properties for the product mixture. Built-in applications account for theoretical rocket performance, Chapman-Jouguet detonation parameters, shock-tube parameters, and combustion properties. Request Software.
