Abstract:

Natural convection as a heat transfer mechanism plays a major role in the functioning of many heat transfer devices, such as heat exchangers, energy storage, thermal management and solar collectors. All of these have a large impact on the generation of solar power. Considering how common these devices are not only in power generation cycles, but in a majority of other thermal uses it is clear that increased performance for natural convection heat transfer will have consequences of a high impact. As such, the purpose of this study is to experimentally study the natural convection heat trans

Abstract:

Cette thèse a pour objectif d’étudier les performances thermiques et rhéologiques des ferrofluides sous champ magnétique pour des applications de refroidissement. L’approche adoptée dans cette thèse est de nature macroscopique, et est basée sur plusieurs études expérimentales. Cette caractérisation des performances des ferrofluides est focalisée sur trois aspects : i) étude de la rhéologie ii) étude de la convection forcée iii) étude la conductivité thermique. Différents outils de caractérisation correspondant à chaque domaine d’étude ont été développés. Dans le domaine de la rhéologie, une ce

Abstract:

This diploma thesis focuses on the preparation of the liposomes, containing lipids with gadolinium, which are used for a contrast magnetic resonance imaging. The liposomes were prepared by the lipid film hydration followed by an extrusion and also by a new nanofluid mixing method on the NanoAssemblr Benchtop. The preparation technology has been optimized for parameters such as the composition of lipids, the flow rate ratio and total flow rate. The method of modification of the liposomes surface by gadolinium complexes has been developed. This method is using a conjugation reaction between the

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2009.<br>Includes bibliographical references.<br>In this work we studied the focusing and trapping of submicron, nonmagnetic species immersed in a magnetic nanofluid under applied magnetic fields. Focusing was achieved using two pairs of permanent magnets, which forced submicron fluorescently-tagged polystyrene beads to focus in the region between the two magnet pairs. Size-based trapping was achieved using a microchip that produced spatially increasing magnetic field gradients that trapped flowing polystyre

Abstract:

Magnetic nanofluid (MNF) is one special kind of nanofluid which possesses both magnetic and fluid properties. Nowadays, extensive attention has been focussed on development of thermal applications. Investigations of magnetic hyperthermia are emerging as a new frontier in studies of cancer therapy. The theory of treatment is based on the fact that magnetic nanoparticles produce heat under an AC magnetic field via a mechanism called magnetic losses. Facing with the present technical limits and growing demands for safe treatment, researchers have realized the advantage of assembling superparamagn

Ce travail vise à approfondir l’utilisation de nanoparticules magnétiques (NPM) en suspensions colloïdales en tant qu’agitateurs nanométriques pouvant manipuler le mélange à l’échelle micrométrique lorsque soumis à des champs magnétiques. D’abord, les structures cohérentes émergeant de la rotation de NPM sont observées par microscopie et sont quantifiées à l’aide d’une analyse multi-résolution basée sur les transformées en ondelettes, démontrant l’effet significatif des paramètres étudiés sur la génération de structures cohérentes vorticales à l’intérieur du fluide.
