TB 26-04 Updates and Modernization of NASA’s Chemical Equilibrium with Applications (CEA) Code
NASA has modernized its Chemical Equilibrium with Applications (CEA) code from the legacy CEA2 to CEA v3. This update transitions the software to an object-oriented architecture with expanded data and interface support.
Why it matters
Engineers can now perform large-scale propulsion trade studies much faster using modern programming languages. It also enables analysis of next-generation fuels, including green propellants and sustainable aviation fuels.
The details
- CEA v3 supports interfaces for Python, C, MATLAB, and Excel.
- The thermodynamic database now includes n-Butanol and green propellant constituents.
- Multi-case workflows can be approximately 800 times faster than in CEA2.
