CoolProp is an extensive C++ library (with wrappers for Python, MATLAB, Excel, etc.) providing thermophysical properties for a vast range of pure fluids, pseudo-pure fluids, and humid air.
It’s indispensable for researchers and engineers who need precise property data integrated into their custom calculations or software.
Phases (related to DDBST – Dortmund Data Bank)
For in-depth phase equilibria work. (Data often referenced via the Dortmund Data Bank)
While the complete DDBST database is commercially licensed, its community actively supports open-source tools and methods to access and utilize publicly available thermodynamic data, particularly phase equilibrium data like VLE, LLE, and SLE.
Computational Fluid Dynamics (CFD)
CFD is vital for understanding fluid flow, heat transfer, and chemical reactions within equipment. Open-source CFD tools offer immense power and customization.
| Tool Name | Feature | Website Link |
|---|---|---|
| OpenFOAM | Highly customizable, powerful for complex flows | openfoam.org |
| Salome Platform (with Code_Saturne) | Full pre/post-processing & CFD solver workflow | salome-platform.org |
OpenFOAM (Open Field Operation and Manipulation)
The C++ toolbox for custom CFD solutions. (OpenFOAM Official Website)
OpenFOAM is not just a solver; it’s a complete library for building custom numerical solvers to tackle a wide range of CFD problems, including turbulence, multiphase flows, and reacting flows.
Its unmatched flexibility makes OpenFOAM a powerful choice for advanced simulation needs. However, this flexibility comes with a steeper learning curve, making it especially suited for researchers and experienced CFD practitioners.
