Sentences with word «constructal»

«Law of physics governs airplane «evolution»: Constructal law explains progression of passenger jets, sets guidelines for future aircraft.»

The bold above is my emphasis, as it demonstrates a principle of constructal theory - the optimal distribution of imperfection.

Interesting IBM's tree channel structure for distribution of the paste leaves a familiar constructal design on the paste itself - This is an image of what the paste looks like after it is pressed onto the chip.

The application of a bottom up constructal approach led to these shapes - and to a cooling structure that is more efficient than anything out there today.

You might've been following Timothy's series on Constructal Theory, which he dubbed «the inverse of Biomimicry.»

So, what can we build with constructal theory?

You can see below another hierarchical «tree» structure from Adrian Bejan's earlier work on constructal trees as heat exchange - where a single contact draws heat from a rectangular area.

You can see constructal organization throughout the design, from the vascular - like structure for the inlet and outlet tree to the hierarchical forest - like structure of channels that spread the coolant paste most efficiently.

Bejan's Constructal Law addresses the fundamental principle of physics that underlies the evolution of flow systems as they change in design over time to increase flow access.

Likewise, constructal theory provides a way to make shapes, from the bottom up.

«It would have had to adhere to the constructal design rules to succeed.»

The constructal law was developed by Bejan in 1996 and states that for a system to survive, it must evolve to increase its access to flow.

Constructal law has also dictated the main design features needed for aircraft to succeed; the engine mass has remained proportional to the body size, the wing size has been tied to the fuselage length, and the fuel load has grown in step with the total weight.

Evolution is a universal phenomenon encompassing technology, river basins and animal design alike, and it is rooted in physics as the constructal law.»

«The Constructal Law extends the power of physics over all of the phenomena of evolutionary design and organization, from geophysics to biology, technology, and social organization,» Bejan said.

This inspired Adrian Bejan, the J.A. Jones Distinguished Professor of Mechanical Engineering at Duke University, who in 1996 discovered the Constructal Law, to provide an answer.

Instead of looking to nature or biology to guide design, constructal theory starts from the understanding of the simple constructal law

A new theory, and possibly a new law of physics, Constructal theory can be understood as the inverse of biomimicry.

The operating temperature of a «constructal» system as the climate is set by the interaction of various homeostatic mechanisms with the physical limitations imposed by the system itself.

There's a good exposition of climate as a heat engine by Adrian Bejan, discoverer of the Constructal Law, here (PDF).

By refining only little the constructal theory model, you can find other very large scale features of the real system.

This is a constructal design.

Constructal theory can help us understand nature, and teach us how to design like nature.

This is not the only application of a constructal approach, far from it.

IBM sought to increase the efficiency of their cooling system, and a scientist versed in biology, computers, and constructal theory took them down the path to a radical evolution in design that has demonstrated cooling power densities of up to 370 Watts per square centimeter with water as coolant (Six times beyond current limits of air - cooling technology - with less energy).

The idea of a resilient optimized system is found throughout the sustainability literature, from Biomimicry to Constructal Theory - successful systems evolve to optimize rather than maximize.

Constructal theory provides the tools engineers need to create sustainable, and beautiful technology.

He confirmed that constructal theory, along with other optimization and creative techniques, played a role in the teams final design.

Applications of constructal theory are limitless, but one significant constructal approach is to design from a finite size (small) and build up to larger optimized structures.

The constructal website features scientific applications from social dynamics and the structure of coral colonies, to climate models and how dust aggregates form in the atmosphere.
