TLDR
In this article, the authors apply the constructal method to the discovery of the optimal distribution of discrete heat sources cooled by laminar natural convection, where the global objective is to maximize the global conductance between the wall and the fluid or to minimize the hot-spot temperatures when the total heat generation rate and global system dimensions are specified.About:

Constructal theory of generation of configuration in nature and engineering
Adrian Bejan,Sylvie Lorente +1 more
TL;DR: Constructal theory is the view that the generation of flow configuration is a physics phenomenon that can be based on a physics principle (the constructal law): "For a finite-size flow system to persist in time (to survive) its configuration must evolve in such a way that it provides an easier access to the currents that flow through it".

Constructal Theory: From Engineering to Physics, and How Flow Systems Develop Shape and Structure
TL;DR: Constructal theory and its applications to various fields ranging from engineering to natural living and inanimate systems, and to social organization and economics, are reviewed in this paper, where the relation between the constructal law and the thermodynamic optimization method of entropy generation minimization is outlined.

Natural convection in rectangular enclosures heated from below and symmetrically cooled from the sides
TL;DR: In this article, the steady natural convection in an enclosure heated from below and symmetrically cooled from the sides is studied numerically, using a stream function-vorticity formulation.
Shape and Structure
TL;DR: In this article, a short theoretical overview of the effects of particle microphysics on particle single-scattering characteristics is presented. But, the assumption of sphericity is rarely made after first having studied the effect of nonsphericity and having concluded that they are negligible.
