Hybrid URANS-LES modeling for the simulation of turbulent flows

open access: yes, 2018
Most of the flows occurring in nature are turbulent. The same can be said about flows of industrial interest. Thus, the differential mathematical modeling of fluid flows enables us to better understand the physical phenomena involved in its occurrence,

Convolutional-neural-network-based DES-level aerodynamic flow field generation from URANS data

open access: yesAIP Advances, 2023
The present paper culminates several investigations into the use of convolutional neural networks (CNNs) as a post-processing step to improve the accuracy of unsteady Reynolds-averaged Navier–Stokes (URANS) simulations for subsonic flows over airfoils at

Patient‐Specific Computational Fluid Dynamics Modeling of Airway Collapse in Infants With Robin Sequence

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 9, September 2026.
This study presents a novel method to analyze the airflow dynamics across the full respiratory cycle in Robin Sequence infants with upper airway obstruction or collapse. It uses 4DCT‐derived airway anatomy and wall movement combined with Computational Fluid Dynamics simulations.

Turbulent flow simulation using hybrid LES/URANS turbulent model by boundary element method [PDF]

open access: yes, 2014
V doktorski disertaciji se posvečamo razvoju hibridnega LES/URANS turbulentnega modela na osnovi metode robnih elementov (MRE) za simulacijo turbulentnega toka tekočine. Za izračun toka tekočine rešujemo sistem Navier-Stokesovih enačb zapisan v hitrostno-

Modélisation d’un écoulement pulsatif et oscillatoire autour d’une pale d’éolienne HAWT Application au décrochage dynamique

open access: yesRevue des Énergies Renouvelables, 2015
L’étude d’une turbine éolienne à axe horizontal (HAWT) soumise à des conditions de fonctionnement en présence de vent est très complexe, car la machine est soumise à une variation instantanée de la vitesse et de la direction du vent, qui peut conduire ...

Protections and Rights: An Intersectional and Diachronic Perspective on Women and the Law in Latin American History

open access: yesHistory Compass, Volume 24, Issue 4, August 2026.
ABSTRACT In just a few decades, historiography on gender and law in Latin America has grown from foundational works establishing the dimensions of women's legal status in colonial compilations and later national codes to scholarship that considers the distinctions among different social groups of women and traces women as active agents in pluralistic ...
