Hi all,


I am working with bio-heat transfer simulation using chtMultiRegionSimpleFoam solver.



I want to implement kappa (thermal conductivity) as a function of temperature.


I did not have any idea related to variable thermal conductivity. So, I watched this beautiful video where the thermal conductivity as a function is explained.

Now, I would like to implement kappa as a variable parameter such that as the temperature is solved, it should solve kappa also. As of now, the thermo-physical properties is as follows:


Code:

mixture
{
    specie
    {
      molWeight   0;
    }

    transport
    {
        kappa   0.51;
    }

    thermodynamics
    {
        Hf      0;
        Cp      3770;
    }

    equationOfState
    {
        rho     1050;
    }
}
Any leads towards a light on variable thermal conductivity in bioheat transfer equation will be appreciated.
