AGA8 Detail

Python Implementation of AGA8 DETAIL method for calculating gas compressibility factor, Z from P, T and gas composition.

Notes:

• Code refactored from the C++ DETAIL code in file Detail.cpp from this repository - https://github.com/usnistgov/AGA8

• Implementation is tested on the same test inputs used in the C++ code, see main.py input P, T and x.

• Python implementation of DensityDetail() and PropertiesDetail().

Setup

1. create .venv using the instructions inside the setup_venv.sh script OR run the shell script using the bash cmd: sh setup_venv.sh
2. run command pip install -e ./src to install the AGA8 package (in editable mode).
3. Choose what inputs, P, T and x you want to run the AGA8 Detail method on and add them to the main.py
4. Run main.py and output Z and approximated P are printed to the screen

Testing

All tests for AGA8Detail are inside the /tests folder. The tests cases are split into 2:

• Known examples from original C++ code (https://github.com/usnistgov/AGA8)
• Known examples from UniSim simulation
