Constructal Design of Thermal Systems
Constructal theory and design accounts for the universal phenomenon of generation and evolution of design [1, 2]. Constructal theory has been used to explain deterministically the generation of shape in flow structures of nature (river basins, lungs, atmospheric circulation, animal shapes, vascularized tissues, etc.) based on an evolutionary principle of flow access in time. That principle is the Constructal law: “for a flow system to persist in time “to survive,” it must evolve in such way that it provides easier and easier access to the currents that flow through it” . This same principle is used to yield new designs for electronics, fuel cells, and tree networks for transport of people, goods, and information . The applicability of this method/law to the physics of engineered flow systems has been widely discussed in recent literature [4–7].
