NSRDSfunction coefficients a,b,c etc in sprayFoam
 

Dear OpenFoamer,

does anyone know how I can find the coefficients in the NSRDSfunctions in order to define a new liquid? I need Isobutane for my simulation with the exact properties. I already compiled the new liquid, but I am missing the right coefficients and I am kinda struggling with the search.

Thanks in advance

Moe

I have similar problem. Did you succeed to find the reference?

No, I wrote an optimization tool in order to use other reference data points with the same functions in openfoam

Reference for NSRDSfunctions
 

I found most of the properties in "Perry's Chemical Engineers' Handbook" by Don W. Green, Robert H. Perry.

I cannot tell whether Isobutane is listed there or not.
