Hi,
I am modeling in chtMultiRegionFoam and i am confused with solidThermophysical properties and Thermophysical properties folders. here are two of folders, at first consider solidThermophysical properties folder :

{
//- thermo properties
rho rho [1 -3 0 0 0 0 0] 2500;
Cp Cp [0 2 -2 -1 0 0 0] 750;
K K [1 1 -3 -1 0 0 0] 1.4;

//- radiation properties
kappa kappa [0 -1 0 0 0 0 0] 0;
sigmaS sigmaS [0 -1 0 0 0 0 0] 0;
emissivity emissivity [0 0 0 0 0 0 0] .88;

//- chemical properties
Hf Hf [0 2 -2 0 0 0 0] 0;
}

what are kappa and simaS and Hf? what is the Hf's unit?

and here is one of thermophysical properties folder:


mixture
{
specie
{
nMoles 1;
molWeight 28.97;
}
thermodynamics
{
Cp 1007.526;
Hf 0;
}
transport
{
mu 1.908068e-05;
Pr 0.705159;

}

What are the units of Cp , Hf , mu ?

no body have not faced with thermophysical properties and solidthermophysical properties?!!

They are all in the International System of units. The user guide helps you a little.

Thank you Lorenzo. in some Froums there was a hot discussion on these units in some cases. so i was not sure. thank you again
