Presentation Transcript

  1. Adrian Bejan, 1996 Constructal Theory

  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." -Bejan, 1996- Constructal Law

  3. Constructal Theory • Flow systems under size-constraint • Tree architecture predicted • Tree/Vascular/Dendritic

  4. Applications

  5. River delta

  6. Tree (and roots)

  7. Vascular

  8. 3D microvascular

  9. Heat dissipation under skin

  10. Airport

  11. Dendritic

  12. Chip cooling

  13. Towards chip cooling

  14. Heat transfer (cooling)

  15. Combustor

  16. Heat exchanger design

  17. Cross flow heat exchanger

  18. From principle to shape

  19. Principles • Every system will remain imperfect • The best that can be done is to optimally distribute imperfections • Imperfections distribute to the smallest scale of system • This optimal distribution will result in the geometry/shape of the system • The perfect form is the least imperfect form possible.
