Dear All,

how about thermophysicalProperties dictionary?

How can I modify it if - for instance - I'd like to use water instead of air?

Code:
air 
{ 
    specie 
    { 
        nMoles          1; 
        molWeight       28.96; 
    } 
    thermodynamics 
    { 
        Cp              1004.5; 
        Hf              2.544e+06; 
    } 
    transport 
    { 
        mu              1.8e-05; 
        Pr              0.7; 
    } 
}
Could you help? Thanks a lot,
Samuele

the best way to copy this file from this tutorial case

tutorials/heatTransfer/chtMultiRegionFoam/multiRegionLiquidHeater/constant/bottomWater/thermophysicalProperties

it is like this
Code:
thermoType
hRhoThermo<pureMixture<constTransport<specieThermo<hConstThermo<incompressible>>>>>;

mixture
{
    specie
    {
        nMoles          1;
        molWeight       18;
    }
    equationOfState
    {
        rho             1000;
    }
    thermodynamics
    {
        Cp              4181;
        Hf              0;
    }
    transport
    {
        mu              959e-6;
        Pr              6.62;
    }
}
happy Foaming
