Thermal contact resistance with variable thickness
 

Hello everyone,

I am trying to model the contact resistance between two bodies. I know that the "turbulentTemperatureCoupledBaffleMixed" is the way to go except I have a unique issue where the thickness between the two objects varies.

My question is: Is it possible to simulate a variable thickness for the thermal contact resistance? And if so, how?

Unfortunately I cannot share the case file as it is sensitive but this is what I have in my 0/T folder for the said BC:

targetToCopper
{
type compressible::turbulentTemperatureCoupledBaffleMix ed;
value $internalField;
Tnbr T;
kappa solidThermo;
kappaName none;
thicknessLayers (2.5e-7); //Use average since cannot make variable
kappaLayers (0.016);
}

Basically what I want is to have my layer thickness follow a certain function dependent on coordinates, for example:

thickness = f(x,z coordinates)

Any help is definitely appreciated. Thanks!
