NSRDS functions, liquid properties
 
Hallo Foamers,

the liquid properties of C10H22 are defined in the file
.../src/thermophysicalModels/liquids/C10H22/C10H22.H

The density is calculated with the NSRDS function 5 in
.../src/thermophysicalModels/thermophyicalFUnctions/NSRDSfuntions/NSRDSfunc5/NSRDSfunc5.H

Here it seems, that the density is only dependent on temperature, and not on pressure. Is the pressure dependency of density taken into account in OpenFoam?

All answers welcome.
Markus

I worked on kerosene(C12H26). i had the similar doubt when i started the work.
In the present 1.7.x code, the density depends only on temperature. i don't think it is too difficult to make it function of both T & P.

Do you have any suggestions how this could be done?
