The void spaces of a porous structure can be interconnected or not. In the latter case the void spaces are disconnected “inclusions” that do not allow a flow to permeate through the porous structure. When the inclusions are large, the flow inside each fluid-filled inclusion may play an important role in the global transport of heat and mass through the structure. This is especially true in coarse cavernous structures encountered in building design.
