I investigated some fluid properties and I found a strange low density for heptane used in OpenFOAM.
In src/thermophisicalModels/liquids/C7H16 is said that density is described by NSRDSfunc5 with coefficients (61.38396836, 0.26211, 540.2, 0.28141).
In src/thermophysicalModels/thermophisicalFunctions/NSRDSfunctions/NSRDSfunc5.h is given the function:
return a/pow(b,1+pow(1-T/c,d))
When I print this on a graph, I obtain a density that is lower than 360kg/m3, while I think it should be over 700kg/m3.
Beside other sources, the NIST pages on the web http://webbook.nist.gov/chemistry/fluid/
conferm that it should be around 700kg/m3.
Is it a mistake or I am missing something?
