Heat transfer through a chimney
 

Hello all,

I am modeling 2D heat transfer through a chimney. The wall of the chimney is taken into consideration and the continum boundary type given is 'solid'. While the interior of the chimney is given a continum boundary type, 'fluid'

For the boundary condition at the external part of the wall exposed to ambient, I used convection.

Does anyone know what i should put as boundary condition for the internal part of the wall that is exposed to the flow of hot air in the chimney?

Thanks in advance!

The only options available are: heat-flux, temperature or coupled.

You should choose coupled
