Constructive Tensor Field Theory [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2016
We provide an up-to-date review of the recent constructive program for field theories of the vector, matrix and tensor type, focusing not on the models themselves but on the mathematical tools used.

Constructal theory of pattern formation [PDF]

open access: yesHydrology and Earth System Sciences, 2007
This review article shows that the occurrence of macroscopic flow configuration is a universal natural phenomenon that can be explained and predicted on the basis of a principle of physics (the constructal law): "For a flow system to persist in time

Geometric optimization of bodies submitted to an intense heat flux using bifurcated channel nets

open access: yesVetor, 2010
The present work studies the geometric optimization of a body submitted to intense heat flux. The body to be optimized is refrigerated by a ducts system whose circulating fluid will remove the heat.

Use and validity of principles of extremum of entropy production in the study of complex systems [PDF]

open access: yes, 2014
It is shown how both the principles of extremum of entropy production, which are often used in the study of complex systems, follow from the maximization of overall system conductivities, under appropriate constraints.

Multi-Objective Constructal Design for Square Heat-Generation Body with “Arrow-Shaped” High-Thermal-Conductivity Channel

open access: yesEnergies, 2022
Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in the previous literature, we performed multi-objective optimization (MOO) with maximum temperature difference (MTD ...

Constructal Theory: A Tool for Ergonomics [PDF]

open access: yes, 2015
Constructal theory proposes to see living bodies as machines that are subjected to constraints, which are constructed with a goal, an objective, which is to obtain maximum efficiency.
