Description

The externalWallHeatTransfer boundary condition applies a heat flux condition to the temperature on an external wall by a fixed (total) heat transfer coefficient. It is required to supply the ambient temperature Ta [K] on the outside of the CFD domain and heat transfer coefficient h [W/m^2/K] between the ambient fluid and the wall. The thermal resistance of the (layered) wall itself is specified through the lists kappaLayers math[W/m/K] and thicknessLayers [m] entries specifying thrmal conductivity and thickness of each layer.

This boundary condition is based on the externalWallHeatFluxTemperature as used by OpenFOAM.

Restrictions
