Mathematical Model of a Constructal Coanda Effect Nozzle [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2016
This paper analyses the ACHEON Coanda effect nozzle for aircraft propulsion, based on the dynamic equilibrium of two jet streams. The ACHEON concept, and, in particular, the HOMER nozzle, which is its main component, are presented, together with the ...

How the thermal environment shapes the structure of termite mounds [PDF]

open access: yesRoyal Society Open Science, 2020
A computational model has been developed to predict the role of environment in the forms and functions of termite mounds. The proposed model considers the most relevant forces involved in the heat transfer process of termite mounds, while also reflecting

Climate change, in the framework of the Constructal Law [PDF]

open access: yes, 2011
Here we present a simple and transparent alternative to the complex models of earth’s thermal behaviour under time-changing conditions. We show the one-to-one relationship between changes in atmospheric properties and time-dependent changes in ...

Is the Evolution of Energy System Productive Structures Driven by a Physical Principle?

open access: yesFrontiers in Sustainability, 2021
The aim of the paper is to identify the consequence of the Constructal Principle in the field of Thermoeconomics of (energy) production systems. This Principle has been recently formulated as an extension of the Maximum Entropy Production Principle and ...

Constructal Evaluation of Polynomial Meta-Models for Dynamic Thermal Absorptivity Forecasting for Mixed-Mode nZEB Heritage Building Applications

open access: yesEnergies, 2022
The intelligent and appropriate regulation of indoor temperatures within heritage buildings is crucial for achieving nearly Zero-Energy Building (nZEB) standards, since the technical improvement of the envelope and the overall shape of heritage buildings

Constructal law & thermoeconomics [PDF]

open access: yesInternational Journal of Heat and Technology, 2016
In spite of evident differences, Constructal Theory and Thermoeconomics (in particular thermoeconomic optimization) have also some similarities. For instance, they both suggest the optimal allocation of two different types of losses: high permeability vs.
