Modeling Fluid dynamics and Aerodynamics by Second Law and Bejan Number (Part 1 - Theory) [PDF]

open access: yesINCAS Bulletin, 2019
Two fundamental questions are still open about the complex relation between fluid dynamics and thermodynamics. Is it possible (and convenient) to describe fluid dynamic in terms of second law based thermodynamic equations?

Dendritic design as an archetype for growth patterns in Nature: fractal and constructal views [PDF]

open access: yesFrontiers in Physics, 2014
The occurrence of configuration (design, shape, structure, rhythm) is a universal phenomenon that occurs in every flow system. Dendritic configuration (or tree-shaped configurations) is ubiquitous in nature and likely to arise in both animate and ...

Numerical study on equilibrium stability of objects in fluid flow — A case study on constructal law

open access: yesCase Studies in Thermal Engineering, 2019
Stability of objects in fluid flow is an interesting and significant subject in many fields. From thermodynamics point of view, the constructal law by Bejan et al.

The influence of convective exchanges on Coandã effect [PDF]

open access: yesINCAS Bulletin, 2019
Modeling Coandã effect has been a fundamental issue in fluid dynamic research in the XX century. It has lost some interest because of the improvement in CFD, even if it could be still important in the area of the preliminary design of aerodynamic devices

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 ...

Hierarchical Modeling of the Liver Vascular System

open access: yesFrontiers in Physiology, 2021
The liver plays a key role in the metabolic homeostasis of the whole organism. To carry out its functions, it is endowed with a peculiar circulatory system, made of three main dendritic flow structures and lobules.

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
