HydDown - 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.

HydDown - 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.

HydDown - 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.
