handle thin material or thermal contact resistance

sven82 · February 21, 2011, 05:47

hello foamers,

at the moment I work with CFX on a cht-simulation
this case got a thin material with a thermal contact resistance
on a patch, only on the patch.
So that the patch imitadet the material through a thermal contact resistance.

The question is got OpenFOAM such a function?

Thanks
Sven

Hi Sven,

no, unfortunately OF has not such a function.

Regards,
Toni

sounds really pity,

got anyone a idea how cfx handle this numerical
in the code? or where I can find it ?

for the coupled patches I work with turbulentTempCoupledBaffle
this patch where calculate the wall temperature based on delta,T and K.
A edit in this cases sounds logical for me.

In the Ansys tutorials you can find the theory for this problem.

What the best way is to implement it into OF I don't know.
