On the Svelteness as an Engineering Tool in Constructal Design: A Critical Review

open access: yesApplied Sciences, 2022
The application of Constructal theory to the flow design in engineering applications connects the channels’ architecture with their freedom to morph.

Theory Construction [PDF]

open access: yes, 2012
Theory construction is a process, i.e., a set of state changes by an autonomous agent, or by an organism composed of several autonomous agents. In the first case, we may recall the approach of Pierce (1931) that considers three logical operations (inference rules) on a knowledge base, i.e., a set of propositions asserted to be valid: abduction ...

Constructal design of a nanofluid cooling channel with sidewall ribs and cavities in a rectangular heat generation body

open access: yesCase Studies in Thermal Engineering, 2023
The heat dissipation optimization of electronic devices with cooling channels is a hot research issue. A nanofluid cooling channel (CCL) model with sidewall ribs and cavities in a rectangular heat generation body is established.

Biophilic urban developments following dynamic flows of tree-shaped architectures [PDF]

open access: yes, 2015
Latest theories and practices in Biophilic designs of the urban space regard the urban fabric as being composed of several interrelated layers of energetic structure influencing each other in a non-linear manner primarily.

Constructive matrix theory [PDF]

open access: yesJournal of High Energy Physics, 2007
We extend the technique of constructive expansions to compute the connected functions of matrix models in a uniform way as the size of the matrix increases. This provides the main missing ingredient for a non-perturbative construction of the $ ^{\star 4}_4$ field theory on the Moyal four dimensional space.

Constructal view of scaling laws of river basins [PDF]

open access: yes, 2006
River basins are examples of naturally organized flow architectures whose scaling properties have been noticed long ago. Based on data of geometric characteristics, Horton [Horton, R.E., 1932. Drainage basin characteristics. EOS Trans. AGU 13, 350–361.],

Improving Thermal Performance of Rectangular Microchannel Heat Sinks using Porous Layer: CFD Simulation and Optimization [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
Microchannel heat sinks are very widely used due to their high heat transfer coefficients and low refrigerant requirements. Nevertheless, microchannel heat sinks still perform sub-optimally when it comes to thermal performance.

Thermodynamic optimization of global circulation and climate [PDF]

open access: yes, 2005
The constructal law of generation of flow structure is used to predict the main features of global circulation and climate. The flow structure is the atmospheric and oceanic circulation.
