Fluid Dynamics

A new pseudo-spectral methodology without numerical diffusion for conducting dye simulations and particle residence time calculations

Dye experimentation is a widely used method in experimental fluid mechanics for flow analysis or for the study of the transport of particles within a fluid. This technique is particularly useful in biomedical diagnostic applications ranging from…

Microscopic and chemical characterization of seashell co-products for valorization in cementitious materials

In order to reduce the environmental impact of the construction sector, research has been led to use seashell co-products in cementitious materials, showing they could bring better durability properties or be used as limestone filler. First results…

Assimilation de données variationnelle et hybride pour le contrôle thermique en temps réel du procédé de fabrication additive

La surveillance en temps réel d'un système peut être difficile si les phénomènes qui se produisent sont multi-physiques et multi-échelles comme c'est le cas de la fabrication additive. L'utilisation d'un modèle paramétrique simplifié peut subvenir à…

Thermal and Electron Plasma Effects on Phase Separation Dynamics Induced by Ultrashort Laser Pulses

During ultrafast laser-induced crystallization from glass with a non-congruent composition, a phase separation occurs. The morphology of the crystallized area, inside the heat-affected zone (HAZ), is spectacular showing a bouquet-like structure,…

SEM3D: A 3D High-Fidelity Numerical Earthquake Simulator for Broadband (0-10 Hz) Seismic Response Prediction at a Regional Scale

In this paper, we present SEM3D: a 3D high-fidelity numerical earthquake simulator that is tailored to predict the seismic wave field of complex earthquake scenarios from the fault to the epicenter site. SEM3D solves the wave-propagation problem by…

Modelling of a PsD hybrid test on a RC column/beam junction combining a multifibre beam model and a POD-ROM approach

In this paper, a pseudo dynamic (PsD) hybrid experimental setup allows for assessing the nonlinear behaviour of a reinforced concrete (RC) column/beam junction under earthquake is proposed. The specimen is linked to a numerical substructure made of…

Une approche multi-échelle d'une méthode de décomposition de domaine mixte pour la simulation magnétostatique 3D

Pour répondre aux besoins numériques d'optimisation de machines tournantes, nous proposons d'adapter la méthode LATIN avec sous-structuration à la résolution des équations de la magnétostatique en conservant les aspects mixte et multi-échelle de la…

Experimental and numerical investigation of drying rate impact on moisture loss, exchange coefficient and drying shrinkage of cement paste

Assessment of moisture content evolution and drying shrinkage is important for the long-term operation of large concrete structures. This paper evaluates the impact of size and boundary conditions in predicting mass loss and drying shrinkage of…
