I am trying to implement a heat conduction model, in the planar direction of a thin wall. Unfortunately, I cannot mesh the thickness of the wall since the computational requirements would be enormous.

I am using the chtMultiRegionFoam solver (openFOAM v2012). I have a fluid (air) and a solid domain. In the boundary between them I use the turbulentTemperatureCoupledBaffleMixed boundary condition. A thin wall exists at the bottom of both regions (all the other external boundaries are insulated).

A simple schematic of what I want to do is presented here:


Do you think it is possible to implement a heat conduction along the thin wall in openFOAM (without meshing the thickness of wall)? A similar model (Shell Conduction) is available in FLUENT: https://www.afs.enea.it/project/nept...ug/node471.htm. I was thinking to use the turbulentTemperatureCoupledBaffleMixed bc (just like the boundary between the two domains). Does anyone has implemented this? Is there any other, more appropriate, boundary condition?

Thanks for your time!
