Adrian Bejan - Constructal Law  Duke Universisty

The constructal law is the law of physics that accounts for the phenomenon of evolution (configuration, form, design) throughout nature, inanimate flow systems and animate systems together.

The constructal law was stated by Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke University, in 1996 as follows1, 2:

 "For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it."

 The constructal law places the concepts of life, evolution, design and performance in physics, which is in the broadest scientific arena. The constructal law is the law of physics of life and evolution3-5.

The constructal law accounts for the arrow of time6, which is the direction of the evolution of flow organization over time.

Constructal theory   ScienceDaily


The constructal theory of global optimization under local constraints explains in a simple manner the shapes that arise in nature.

It is the thought that flow architecture comes from a principle of maximization of flow access, in time, and in flow configuration that are free to morph.

The constructal law proclaims a tendency in time about the generation of animate and inanimate flow systems: "the maximization of access for the currents that flows through a morphing flow system. " This theory replaces the belief that nature is fractal, and allows one to design and analyse systems under constraints in a quest for optimality.

This theory allows the design and understanding of natural systems, thermal dissipators, communication networks, etc.

Exposing a solar panel to the sun and extracting electricity directly maximizes the flow of energy from the sun to human uses.

"It is not necessary to have hope in order to persevere."
