Evaluation of the PANS method for the prediction of the fluid flow in a cyclone separator

Zaher Bitar, David Uystepruyst, François Beaubert, Damien Méresse, Céline Morin

The simulation of the cyclone separation efficiency can rapidly become very expensive in time of calculation, which is not suitable for industrial application. The prediction of the complex turbulent gas flow inside a cyclone is necessary to estimate its pressure drop, its characteristics and…

A Novel 3D Topography Stitching Algorithm Based on Reflectance and Multimap

Julie Lemesle, Robin Guibert, Maxence Bigerelle

Surface topography is an efficient tool for the understanding of physical phenomena, especially if multiscale roughness analysis is performed. However, the observable scale range in a topography measured with 3D optical profilometers is quite limited. Therefore, all scales linked to a physical…

An efficient scenario penalization matheuristic for a stochastic scheduling problem

Michel Vasquez, Mirsad Buljubasic, Saïd Hanafi

We propose a new scenario penalization matheuristic for a stochastic scheduling problem based on both mathematical programming models and local search methods. The application considered is an NP-hard problem expressed as a risk minimization model involving quantiles related to value at risk which…

Highly stable fluorine-free slippery liquid infused surfaces

Anne-Sophie Vaillard, Manon Saget, Flavie Braud, Marc Lippert, Laurent Keirsbulck, Maude Jimenez, Yannick Coffinier, Vincent Thomy

A promising Slippery Liquid Infused Surface (SLIS) has been developed, that is both easy-to-produce and environmentally friendly. Using a double replication method, a 200 µm-thick texturized cross-linked PDMS film was obtained, leading to a grid of micrometric hills and deep wells. A comparison…

A Review on Quality in Use Evaluation of Smart Environment Applications: What’s Next?

Maria Paula Corrêa Angeloni, Káthia Marçal de Oliveira, Emmanuelle Grislin-Le Strugeon, Rafael Duque, Cristina Tirnauca

To guarantee that a software is suitable for its users regardless of age or any disabilities, it is necessary to evaluate it with end users. This task is not always simple for a software system in smart environments, especially in the context of the ones that are used to help keep elderly people…

Vehicle Actuator Fault Detection With Finite-Frequency Specifications via Takagi-Sugeno Fuzzy Observers: Theory and Experiments

Juntao Pan, Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Chouki Sentouh, Sujun Wang, Jean-Christophe Popieul

Abstract This article investigates the design of Takagi–Sugeno (TS) fuzzy model‐based observers for nonlinear systems with parametric uncertainties and unknown inputs. To address this challenging problem, two observers are constructed in cascade. Based on the sliding mode technique, the first…

Design features of the kinematic chain of the ant exoskeleton

Santiago Arroyave-Tobon, Jordin Drapin, Jean-Marc Linares, Pierre Moretto

New challenges in engineering design are about resilience, frugality and sustainability. Nature offers remarkable examples of successful mechanical designs that respond to those constraints. Therefore, biological systems deserve to be explored from a design perspective. The study of design features…

Coupled experimental and offline simulation study of a helicopter rotor in a frigate airwake with active flow control, Étude expérimentale et simulation hors ligne d'un rotor d'hélicoptère dans le sillage d'une frégate avec contrôle actif de l'écoulement

Elvina Derhille, Quentin Gallas, Luc Bordier, Simon Verley, Laurent Keirsbulck

L’appontage des hélicoptères sur les navires de type frégate demande une forte charge de travail de la part des pilotes. Cet article présente l’effet d’un dispositif de contrôle actif, situé le long des arrêtes du hangar, sur la traction rotor le long d’une trajectoire dans l’axe du navire. Les…
