OpenFOAM Coolprop Integration

[Carl Bunge]

Hi everyone,

I am attempting to integrate fluid properties in OpenFOAM through the implementation of temperature, pressure lookup tables.

 

My current attempt of implementing fluid properties has consisted of a pair python codes developed by Luka Denies from TU Delft (https://github.com/ldenies/tabulatedProperties/tree/master/tableGenerator ) which sweep temperature and pressure through the direct implementation of the equation of state. However, when I coded in parahydrogen’s equation of state into this same python structure, the code returns values of h, cp, ect. which are different from Refprop.

 

I foresee the implementation of Coolprop as a more reliable way to create lookup tables for future fluids rather than hard coding the equation of state. I'd really appreciate any progress or tips with Coolprop’s use with OpenFoam and was wondering if anyone has developed method for this integration.

Thank you,

Carl

Differences in h,s,u, are likely due to the reference state: https://github.com/CoolProp/CoolProp/blob/master/FAQ.md, but cp should be the same.  If not, that is a problem that should be fixed.  Are the EOS different between REFPROP and CoolProp?  How does the density look?  Is it the same?

Hi Ian, fellow coolprops,

Please see the following tabularCoolProps class for OpenFOAM 5.x: https://github.com/cbunge/coolPropTableGenerator Please let me know if there are any improvements that can be made.

Thanks,

Carl

Very nice!!!  Can you perhaps cross-post to the OpenFOAM list to let them know about this functionality?  I think there are a lot of folks that might be interested in this capability.

Best,

Ian
