A combined finite volume - finite element scheme for a low-Mach system involving a Joule term

Caterina Calgaro, Claire Colin, Emmanuel Creusé

In this paper, we propose a combined finite volume-finite element scheme, for the resolution of a specific low-Mach model expressed in the velocity, pressure and temperature variables. The dynamic viscosity of the fluid is given by an explicit function of the temperature, leading to the presence of…

Synthesis, crystal structure and magnetic behavior of a new calcium magnesium and iron orthophosphate Ca2MgFe2(PO4)4

Ahmed Ould Saleck, Cyrille Albert-Mercier, Claudine Follet-Houttemane, Olivier Mentré, Abderrazzak Assani, M. Saadi, L. El Ammari

The structure of the new calcium magnesium iron orthophosphate, Ca2MgFe2(PO4)4 was determined from single crystal X-ray diffraction data. It crystallizes in the orthorhombic system, space group Pbca, with all atoms in general positions among which two sites are disordered. The crystal structure of…

La vague dans la matrice, The Wave in the Matrix

Gaëtan Robillard, Caterina Calgaro, Emmanuel Creusé

La Vague dans la matrice examine la relation entre mathématiques et environnement, en particulier la façon dont les sciences du climat inscrivent de nouveaux signes dans le monde. Le travail se matérialise dans un réseau de surfaces en cuivre et de processeurs qui simulent un champ de vagues généré…

A finite volume method for a convection- diffusion equation involving a Joule term

Caterina Calgaro, Emmanuel Creusé

This work is devoted to a Finite Volume method to approximate the solution of a convection-diffusion equation involving a Joule term. We propose a way 5 to discretize this so-called "Joule effect" term in a consistent way with the non linear diffusion one, in order to ensure some maximum…

Development of Surface Acoustic Wave pressure sensors for monitoring concrete structures

Hassan Alhousseini, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Nikolay Smagin, Frédéric Rivart, Marc Poorteman, Maurice Gonon, Gregory Matric, Mohamed Rguiti, Christine Peligris

For many years surface acoustic waves (SAW) have been used in manufacturing electronic components for industrial and sensing applications. Due to the absence of an embedded electronic system and the possibility of wireless communication this technology can offer a great solution for sensing in…

Uniform a priori estimates for elliptic problems with impedance boundary conditions

Théophile Chaumont-Frelet, Serge Nicaise, Jérôme Tomezyk

We derive stability estimates in H2 for elliptic problems with impedance boundary conditions that are uniform with respect to the impedance coefficient. Such estimates are of importance to establish sharp error estimates for finite element discretizations of contact impedance and high-frequency…

Nanotechnology to improve the performances of hydrodynamic surfaces

Ali Ahmed Alshehri, Philippe Champagne, Laurent Keirsbulck, El Hadj Dogheche

ure continues to inspire scientists to adapt solutions in order to satisfy human needs, mainly in the maritime domain with metallic surface corrosion and its mechanical friction. In this research, the source of innovation comes from the lotus leaf and its well-known super-hydrophobicity. In this…

Open-celled silicon carbide foams with high porosity from boron-modified polycarbosilanes

Charlotte Durif, Mélanie Wynn, Maxime Balestrat, Giorgia Franchin, Young-Wook Kim, Anne Leriche, Philippe Miele, Paolo Colombo, Samuel Bernard

Open-Celled silicon carbide (SiC) foams were prepared from a mixture of a boron-modified polycarbosilane as a preceramic polymer and poly(methymetacrylate) (PMMA) microbeads as sacrificial agents. The process consists in the cross-linking of the liquid allylhydridopolycarbosilane (AHPCS, SiC…
