Development of a predictive multi-material and multi-physics model based on volume-of-fluid for simulating wire laser additive manufacturing process

Haijie Chang, Yabo Jia, Hans Boungomba, Hakim Naceur, Laurent Dubar

Wire Laser Additive Manufacturing (WLAM) has been widely applied in production technologies for creation of complex geometry and repairing. This process involves numerous coupled physical phenomena, such as laser-material interaction, phase transformations (solid and liquid), fluid dynamics within…

Enhancing thermal management of GaN transistors with direct oil jet impingement: Experimental insights for high-power electronics

Anas El Amraoui, Riadh Boubaker, Souad Harmand

This study experimentally investigates the cooling performance of oil jet impingement on high-power GaN transistors, focusing on the effects of nozzle geometry (diameter: 0.5 mm, 1 mm; nozzle-transistor distance: 5 mm, 10 mm) and properties of two fluids (a NewOil-A and Siloil M40). At a flow rate…

Enhancing the PI Distribution Network Performance with Hybrid ML Forecasting Techniques Applied to a Case Study of Electronic Products in Thailand

Anirut Kantasa-Ard, Maroua Nouiri

The consumption rate of different products such as electronic devices has drastically increased since the onset of COVID-19 in 2020. This shift in behavior has significantly impacted on the efficiency performance of supply chain in many countries. Using Physical Internet (PI) paradigm as an open…

Base de données stop walking while talking chez des personnes âgées en bonne santé

Anaïs Chaumeil, Mathias Blandeau, Carlos Vazquez, Rachid Aissaoui, Eric Granger

Objectifs : Le paradigme stop walking while talking proposé en 1997 suggère que les personnes âgées fragiles à risque de chute élevé vont s’arrêter lorsqu’une conversation est entamée avec elles lors de la marche. Chez les personnes âgées en bonne santé (non fragiles), nous faisons l’hypothèse d’un…

Évaluation et comparaison d'une double tâche écologique

Anaïs Chaumeil, Mathias Blandeau

Objectifs : L'étude de la marche pendant une double tâche (DT) permet d'obtenir des informations sur le contrôle moteur, notamment pour des personnes âgées. Or la plupart des DT proposées (compter, réciter l'alphabet, réagir à des perturbations, …) ne sont pas représentatives des DT…

Optimization of explicit RKN schemes to minimize spurious reflections from shock wave propagation on non-uniform grids

Emmanuel Creusé, Mamadou N'Diaye, Juliette Venel, Cédric Hubert, Nicolas Leconte

The propagation of shock waves on non-uniform grids appears, for example, in some impact problems of the fast dynamics type, where a finer mesh can typically be employed in regions of interest, leading to mesh ratios that can range from 10 to 20 or even more. Unfortunately, unwanted spurious…
