Numerical simulation of the flow through the blades of a swirl generator

Manel Wannassi, François Monnoyer de Galland

This paper aims at analyzing the dynamics behavior of the flow generated by blade swirlers. Three-dimensional calculations are carried out for different Reynolds numbers and blade angles (θ = 20◦, 30◦, and 45°). Flow field characteristics within the swirler and in the outgoing jet are examined in...

Context-based evaluation of mobile knowledge management systems

Emna Ben Ayed, Christophe Kolski, Houcine Ezzedine

The technological revolution has been accompanied with the appearance of mobile systems. Mobile Knowledge Management Systems (KMS) which introduce a new style of managing organizations using mobile devices, are used in different contexts of use. So, a context based evaluation of such systems...

Control synthesis for polynomial discrete-time systems under input constraints via delayed-state Lyapunov functions

J. L. Pitarch, Jimmy Lauber, Thierry-Marie Guerra, Antonio Sala

This paper presents a discrete-time control design methodology for input-saturating systems using a Lyapunov function with dependence on present and past states. The approach is used to bypass the usual difficulty with full polynomial Lyapunov functions of expressing the problem in a convex way....

Simplex Enhanced Numerical Modeling of the Temperature Distribution in a Hydrogen Cooled Steel Coil Annealing Process

Abdallah Haouam, Maxence Bigerelle, Bachir Merzoug

The temperature distribution of steel coils during annealing process in hydrogen has a significant effect on their quality. It is approached by numerical modelling using the differential equations governing the heat transfers involved. The resolution is performed by the method of finite differences...

«Les enjeux économiques du processus souverainiste catalan»

Orlando Manzano Guerrero

Le 25 septembre 2012, le président du Gouvernement catalan – Artur Mas – annonça la dissolution du Parlement régional et la tenue d'élections anticipées. Il s'engagea en outre, en cas de nette victoire de la coalition qu'il dirigeait, à organiser une consultation populaire visant à...

Residual-based a posteriori error estimates for a nonconforming finite element discretization of the Stokes–Darcy coupled problem: isotropic discretization

Serge Nicaise, Bernardin Ahounou, Wilfrid Koffi Houedanou

In this paper we develop an a posteriori error analysis of a nonconforming mixed finite element method for the coupling of fluid flow with porous media flow. The approach utilizes the same nonconforming Crouzeix–Raviart element discretization on the entire domain (Rui and Zhang, Comput Methods Appl...

Electrical, dielectric and photocatalytic properties of Fe-doped ZnO nanomaterials synthesized by sol gel method

Yacine Cherifi, Ahcène Chaouchi, Yannick Lorgouilloux, Mohamed Rguiti, Abdelaziz Kadri, Christian Courtois

Fe-doped ZnO nanoparticles were synthesized by sol gel technique. Fine-scale and single phase hexagonal wurtzite structure in all samples were confirmed by SEM and XRD, respectively. The band gap energy depends on the amount of Fe and was found to be in the range of 3.11–2.53 eV. The electric and...
