# Hydrogen-Real-Gas-Model In this repository, a new real gas model for hydrogen based on the Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) v10.0 is provided for the use in the simulation software OpenFOAM v2012. *** ## OpenFOAM folder structure  ## Tutorial In a tutorial case of the flow through a critical flow Venturi nozzle, the usage of the new real gas model is shown. For the start of the simulation, do the following steps: 1. run <blockMesh && extrudeMesh> 2. run either: a) <sonicFoam> or b) <decomposePar> and then <mpirun -np 4 sonicFoam -parallel> For the post-processing, you might need to: 3. run reconstructPar (if your case was decomposed before) ## Acknowledgments This work was supported through the Joint Research Project “Metrology infrastructure for high-pressure gas and liquified hydrogen flows”. This project (20IND11 MetHyInfra) has received funding from the EMPIR programme co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme.
