Maximum flow access in heat exchangers, heat generating bodies and inanimate flow systems: Constructal law and the emergence of shapes and structures in thermo-fluid mechanics. Comment on 'The emergence of design in pedestrian dynamics: Locomotion, self-organization, walking paths and constructal law' by Antonio F. Miguel

摘要

The evolution and the emergence of new design theory in thermo-fluid mechanics has led to the generation of shapes and structures in heat generating bodies and heat exchangers, which perform optimally under global constraints. Constructal theory, design and self-organization in nature, ideally, have been adopted as an optimization technique for the development of a procedure that is capable of allocating and optimizing a fixed global space constraint using physical laws. These physical laws define the future way toward emergence of evolutionary design. It has been applied in all facets of life; from humanity and nature to science and engineering. Constructal law is a theory about the time direction of global optimization and it explains in a simple manner shapes that arise in nature. Flow architecture comes from a principle of maximization of flow access, in time, and in flow configuration that is free to morph.
