  1. SHAPE AND STRUCTURE IN ENGINEERING AND NATURE(A. Bejan, Cambridge, 2000)AULA INAUGURALTM721 – Simulação e Controle de SistemasFísicos José Viriato Coelho Vargas, UFPR, Brazil Universidade Federal do Paraná Setor de Tecnologia Departamento de Engenharia Mecânica – DEMEC

  2. SOME IDEAS • Animate and inanimate systems design. Is it appropriate to separate them? • Made from the same chemical elements • Matter <-> Energy • Animate -> inanimate • Inanimate -> animate • Evolution Theory – originally conceived for biological organisms • Constructal Law – unifies all systems design

  3. SCIENTIFIC RESEARCH EXAMPLE International Journal of Heat and Mass Transfer 48 (2005) 4410–4427 Constructal PEM fuel cell stack design J.V.C. Vargas, J.C. Ordonez, A. Bejan

  4. What have we learnt? Slope ~ ¾ Fuel cell design animal design Metabolic rate Animal size
