Experimental Study of the Effect of Water Spray in the Air on Thermal Transfers Along a Plate of an Exchanger

Nihel Grich, Walid Foudhil, Souad Harmand, Sadok Ben Jabrallah

This study is an experimental investigation of the oceanic environment effect on a plate heat exchanger performance. Indeed, an experiment was carried out on a single plate of the exchanger to generate a turbulent airflow in which fine water droplets were injected into a horizontal vein where a…

A review on potentials of coupling PCM storage modules to heat pipes and heat pumps

Saman Rashidi, Hamid Shamsabadi, Javad Abolfazli Esfahani, Souad Harmand

A large portion of world’s final energy consumption is employed in thermal form. The proper techniques can be used to improve the efficiencies of thermal energy systems and decrease the energy consumption. Phase change material (PCM) storage modules can be coupled with different thermal systems to…

Thermal control of electronic components using a liquid around the phase change material

Haythem Shili, Kamel Fahem, Souad Harmand, Sadok Ben Jabrallah

As part of the research in the field of thermal control of electronic components, we confined a phase change material (plastic paraffin) in a liquid and we heated it on one vertical side by a hot plate. The presence of the liquid around the phase change material (PCM) prevents the direct contact…

A class of predefined-time controllers for uncertain second-order systems

Juan Diego Sanchez-Torres, Aldo-Jonathan Muñoz-Vázquez, Michael Defoort, Esteban Jiménez-Rodríguez, Alexander Loukianov

This paper proposes a novel formulation for robust predefined-time stabilisation of a class of second-order systems with matched perturbations. The presented approach allows designing a family of controllers that enforce a predefined-time sliding motion, even in the presence of unknown but bounded…

Numerical study of flow around two spheres filled by a phase-change material

Fatma Ghrissi, Belgacem Dhifaoui, Souad Harmand, Sadok Ben Jabrallah

A numerical simulation using the commercial software “COMSOL Multiphysics” was carried out to study the flow around two fixed spheres filled with a phase-change material (PCM). This work focuses essentially on the process of fusion of the two interactive spheres located at different distances and…

Numerical investigation of several twisted tubes with non-conventional tube cross sections on heat transfer and pressure drop

Bruce Indurain y Urricelqui, David Uystepruyst, François Beaubert, Sylvain Lalot, Asdis Helgadottir

Numerical simulations were performed with the open-source CFD software OpenFOAM to investigate the ability of several configurations of short length twisted tube geometries with non-circular cross-section connected to tubes with circular cross-section to induce a swirling flow. The heat transfer…

Mechanistic insights on ultra-tough polylactide-based ionic nanocomposites

Jean-Emile Potaufeux, Jérémy Odent, Delphine Notta-Cuvier, Rémi Delille, Sophie Barrau, Emmanuel P. Giannelis, Franck Lauro, Jean-Marie Raquez

We report the synthesis and characterization of ultra-tough polylactide-based ionic nanocomposites via melt-blending of commercial polylactide (PLA), imidazolium-functionalized poly(ethylene glycol)-based polyurethane (im-PU) and surface-modified sulfonated silica nanoparticles (SiO2–SO3H) using…

The multi-visit team orienteering problem with precedence constraints

Said Hanafi, Renata Mansini, Roberto Zanotti

We study a new variant of the Team Orienteering Problem (TOP) where precedence constraints are introduced. Each customer has a set of tasks that have to be accomplished according to a predefined order by an heterogeneous fleet of vehicles. If a customer is selected, then all the tasks have to be…

Numerical and Experimental Study of Flow and Convective Heat Transfer on a Rotor of a Discoidal Machine With Eccentric Impinging Jet

Chadia Haidar, Rachid Boutarfa, Mohamed Sennoune, Souad Harmand

Abstract Discoidal rotor–stator systems are especially used in rotating machines and in numerous industrial applications. The design of high-power machine requires compliance with certain cooling-related stresses. Using an air jet impinging on a rotating disk is one way to increase the global heat…
