The Constructal Law governs the phenomena of design and evolution in nature.

The conference explores the unifying power of the Constructal Law and its applications in all the domains of design generation and evolution, from biology and geophysics to social organization, energy sustainability and security.

The conference also covers the Second Law, and how the Constructal fits in Thermodynamics. The Constructal Law and Second Law are self-standing as first principles. Together, they empower Science much more than the Second Law alone.

CLC2019 is the 12th Conference will be hosted by Universidade do Vale do Rio do Sinos, São Leopoldo, RS, Brazil
