Helium: transport properties not implemented #5

Open thorade opened 11 years ago

thorade commented 11 years ago

Helium does currently use transport properties of Butane! Instead, it should use the special helium correlations, but these are not yet implemented.

Comment by @casella: Dynamic viscosity in the Helium model doesn't work, looking at the implementation it seems that the "right" coefficients are missing from the table (only integer numbers show up in the code)

thorade commented 10 years ago

@casella Helium viscosity is now implemented, using the same special hardcoded algorithm as in RefProp. Results have been manualy tested (~20 points) to be identical, you are invited to do further testing. Thermal conductivity will come later.

Thank you Matthis!

We plan to use your model for a library on which we'll be going to publish extensively. Can you point me out the correct citations for your library?

You are welcome! Feel free to submit more issues if there is anything that could be improved. Also, if speed is an issue, I could try working on that. The github repository lists some publications that you could cite: https://github.com/thorade/HelmholtzMedia#library-description
