barotropy 0.4.4

A Python tool for barotropic fluid property modeling.

Barotropy

Enhance your two-phase turbomachinery CFD simulations with barotropy, a Python package designed to create barotropic fluid property models. The barotropic approximation assumes that fluid properties (e.g., density, viscosity, speed of sound) depend solely on pressure, which is a very accurate assumption for most turbomachinery flows. This simplification reduces computational costs while improving convergence reliability in simulations involving complex fluid property variations, such as supercritical CO₂ compressors or two-phase flows in nozzles and turbines.

📦 PyPI package: https://pypi.org/project/barotropy/

📚 Documentation: https://turbo-sim.github.io/barotropy/ (under construction)

🎓 Tutorials: https://turbo-sim.github.io/barotropy/source/tutorials.html
Step-by-step examples for using the barotropic model in CFD solvers like Ansys Fluent and CFX.

Key Features

• Simplified fluid modeling: Generate barotropic models to lower computational cost and enhance solver robustness compared to real-gas fluid property tables.
• Suited for homogeneous two-phase flows: Simulate two-phase flows with one or two-components using the Homogeneous Equilibrium Model (HEM) or the Delayed Equilibrium Model (DEM) assumptions..
• Seamless integration with commercial CFD solvers: Easily export barotropic models as simple expressions ready to be copy-pasted into ANSYS Fluent or ANSYS CFX.

🚀 User installation (via PyPI)

To begin using barotropy, install it via pip:

pip install barotropy

After installation, verify that everything is set up correctly by running the following command in your terminal:

python -c "import barotropy; barotropy.print_package_info()"
