2009 ASHRAE Winter Conference:
Technical Keynote Speaker

Constructal Theory Theorist to Speak at 2009 ASHRAE Winter Conference

• Why are lungs and river basins tree-shaped?
• Why are larger animals faster, stronger and less active?
• Why is there “technology evolution?”  

It can all be explained by “constructal theory.” And the man who developed the theory – which he says can predict how everything flows through time and space – will serve as technical keynote speaker at ASHRAE’s 2009 Winter Conference.

Adrian Bejan, Ph.D., is the J.A. Jones Distinguished Professor of Mechanical Engineering at Duke University. He proposed the theory in 1996 and has since worked to predict with it a wide variety of phenomena, from geophysics to biology and social design. “The main principle of the constructal theory is that in order to persist in time (to survive) a flow system must change such that it flows easier and easier,” he said. “Every flow system has this natural tendency, and is destined to remain imperfect. The theory shows that the emergence of scaling laws in geophysical flow systems is the same phenomenon as the emergency of allometric laws in biological flow systems and that features of evolutionary design in nature can be predicted based on the constructal law.”  For more information, visit http://www.constructal.org/.
