I'm wondering what the best approach is for deciding the heat transfer coefficient (h) for the externalWallHeatFluxTemperature BC. In the tutorials the most common value for it seems to be 10.


I'm using it for modelling the external building walls of a street canyon in an urban city with solar irradiation. It's not multi-region, the solver I'm using is rhoReactingBuoyantFoam.


I have experimental data that I want my temperature curve to mimic. Is trial and error the best approach? Would I get accurate results by using thermal conductivity values of different materials from wikipedia?
