I am trying to do a two-phase boiling simulation in fluent in a rectangular channel including conjugate heat transfer analysis.. I have given constant heat flux BC at the bottom wall and the rest walls are given zero heat flux (adiabatic). Should I mention the wall thickness for all walls in BC setup of fluent for simulating the model or the wall thickness should be kept at 0 (default setting) for conjugate heat transfer analysis? I have attached the screenshot of the wall and fluid with BCs.

If you are not resolving the walls then you can provide a thickness for the walls to model the steady heat conduction through the solids but only in the normal direciton of the walls. Tangetial / transversal heat conduction in not captured by this approach.

You do not need to provide any thickness for the walls in Fluent as they are now resolved and modeled as solid domain!

Fluid Mesh should be much more finer but I recommend to use log-wall type of mesh for stability reasons when using one of Boiling Models (and you are running turbulent).

I am not using turbulent model as my complete flow domain is laminar. I will refine the mesh for fluid but what is long-wall type of mesh?
