HydDown

Hydrogen (or other pure gas phase species) pressure vessel filling and discharge calculations.

All basic functionality for single component gas pressurisation/depressurisation implemented. For steel vessels the results have been validated against experiments from the scientific literature. Rudimentary multicomponent capability.

Alpha

First version working reasonably well with most needed features implemeting. Some work is required to provide meaningful messages to errors in input/yaml. Some convienece features are also lacking such as result arrays stored as pandas dataframe, optimisation/solvers for valve sizing is also lacking. More elaboration on heat transfer correlations is required as well as a transient 1-D heat transfer model to handle other materials than fairly dense metals.

Streamlit app

The first version with basic functionality implemented: testing, input file format, and schema check, calculation class and utility functions. Most calculation methods and combinations are implemeted except fire (variable) external heat load. Some validation pending for filling.

Release for DOI

First release for depressurisation with various methods, including heat transfer etc.
