Combining modern thermodynamics theory branches, including finite time thermodynamics or entropy generation minimization, constructal theory and entransy theory, with metallurgical process engineering, this paper provides a new exploration on generalized thermodynamic optimization theory for iron and steel production processes. The theoretical core is to thermodynamically optimize performances ...

This is a brief in tro duc tion to an en gi neer ing the ory on the or i gin and gen er a tion of geo met ric form in all flow sys tems: the an i mate, the in an i mate and the en gi neered. The the ory is named constructal, and is based on the thought that it is nat u ral for cur rents to con struct for them selves in time paths of greater flow access. It is shown that this pro cess of flow pa...

Here, we show that the most basic features of tree and forest architecture can be put on a unifying theoretical basis, which is provided by the constructal law. Key is the integrative approach to understanding the emergence of "designedness" in nature. Trees and forests are viewed as integral components (along with dendritic river basins, aerodynamic raindrops, and atmospheric and oceanic circu...

In this paper, we use Bejan’s Constructal theory to optimize the geometry of a H-shaped cavity that intrudes into a solid conducting wall. The objective is to minimize the global thermal resistance between the solid and the cavity. Internal heat generation is distributed uniformly throughout the solid wall. The cavity surface is isothermal, while the solid wall has adiabatic conditions on the o...
