ThermoFluidDaten

ThermoFluidDaten is a publicly accessible, community-driven database of thermophysical data for fluids and mixtures. It aggregates experimentally measured properties and validated model predictions to support engineering design, simulation, and teaching in chemical, mechanical, and aerospace disciplines.

The repository covers pure fluids, mixtures, and surrogate systems, including thermodynamic properties such as density, viscosity, thermal conductivity, and heat capacity, as well as surface tension, phase equilibria, critical properties, and transport data like diffusion coefficients and viscosities. It also provides parameters for equations of state and mixing rules, along with phase diagrams and critical curves.

Each dataset is accompanied by metadata, uncertainty estimates, provenance, and quality flags, enabling researchers to assess reliability. Contributions are curated by a community editorial board and aligned with established standards for thermophysical data, ensuring traceability from original sources to end users.

Access is provided through a web API and bulk downloads in CSV, JSON, XML, and NetCDF. Licensing information accompanies each dataset, with open-access terms designed to support academic and industrial use, proper attribution, and versioned data releases.

Practitioners in process engineering, computational fluid dynamics, and education rely on ThermoFluidDaten for reproducible simulations, tool-chain integration, and comparative studies. The project emphasizes transparent provenance, collaborative contributions, and ongoing expansion to cover new fluids and measurement methods.
