This book was released on 2020-03-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis demonstrates the first use of high-speed ultrasound imaging to non-invasively probe how the interior of a dense suspension responds to impact. Suspensions of small solid particles in a simple liquid can generate a rich set of dynamic phenomena that are of fundamental scientific interest because they do not conform to the typical behavior expected of either solids or liquids. Most remarkable is the highly counter-intuitive ability of concentrated suspensions to strongly thicken and even solidify when sheared or impacted. The understanding of the mechanism driving this solidification is, however, still limited, especially for the important transient stage while the response develops as a function of time. In this thesis, high-speed ultrasound imaging is introduced to track, for the first time, the transition from the flowing to the solidified state and directly observe the shock-like shear fronts that accompany this transition. A model is developed that agrees quantitatively with the experimental measurements. The combination of imaging techniques, experimental design, and modeling in this thesis represents a major breakthrough for the understanding of the dynamic response of dense suspensions, with important implications for a wide range of applications ranging from the handling of slurries to additive manufacturing.

Book excerpt: An essential text on practical application, theory and simulation, written by an international coalition of experts in the field and edited by the authors of Colloidal Suspension Rheology. This up-to-date work builds upon the prior work as a valuable guide to formulation and processing, as well as fundamental rheology of colloidal suspensions. Thematically, theory and simulation are connected to industrial application by consideration of colloidal interactions, particle properties, and suspension microstructure. Important classes of model suspensions including gels, glasses and soft particles are covered so as to develop a deeper understanding of industrial systems ranging from carbon black slurries, paints and coatings, asphalt, cement, and mine tailings, to natural suspensions such as biocolloids, protein solutions, and blood. Systematically presenting the established facts in this multidisciplinary field, this book is the perfect aid for academic researchers, graduate students, and industrial practitioners alike.

Download or read book Complex Plasmas And Colloidal Dispersions Particle resolved Studies Of Classical Liquids And Solids written by Alexei Ivlev and published by World Scientific Publishing Company. This book was released on 2012-05-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many fundamental issues in classical condensed matter physics can be addressed experimentally using systems of individually visible mesoscopic particles playing the role of “proxy atoms”. The interaction between such “atoms” is determined by the properties of the surrounding medium and/or by external tuning. The best-known examples of such experimental model systems are two different domains of soft matter — complex plasmas and colloidal dispersions.The major goal of this book — written by scientists representing both complex plasmas and colloidal dispersions — is to bring the two fields together. In the first part of the book the basic properties of the two systems are summarized, demonstrating huge conceptual and methodological overlap of the fields and emphasizing numerous cross-connections between them and their essential complementarity. This “introductory part” should serve to help each community in understanding the other field better. Simultaneously, this provides the necessary basis for the second part focused on particle-resolved studies of diverse generic phenomena in liquids and solids — all performed with complex plasmas and/or colloidal dispersions. The book is concluded with the discussion of critical open issues and fascinating perspectives of such interdisciplinary research.

Available in PDF, EPUB and Kindle. Book excerpt: Ce travail expérimental cherche à mieux caractériser, au moyen des techniques de diffusion de la lumière, la dynamique de certains systèmes colloïdaux, qui montrent un comportement rhéologique complexe. Il s'articule autour de deux points: le rajeunissement et la formation des bandes de cisaillement dans un système colloïdal vitreux, et le phenomène du jamming dans une suspension concentrée de particules chargées. Dans une suspension de Laponite -système modèle pour les colloïdes vitreux- la compétition entre le rajeunissement dû au cisaillement et le vieillissement a été étudié pendant l'écoulement, alors qu'aprés l'arret de l'écoulement deux régimes de vieillissement ont été observés. La localisation du cisaillement a été mis en evidence à des taux faibles de cisaillement global, en mesurant les profils de vitesse du fluide, mesure qui en outre, par ses oscillations, a révélé un comportement de stick-slip. D'autre part dans une suspension concentrée de particules de silice dans le régime de jamming, nous nous sommes interessés à la dynamique des structures induites par l'écoulement et avons mis en évidence la présence de particules plus lentes pendant le cisaillement, puis étudié la relaxation de la dynamique des particules après l'arret de l'écoulement en fonction des contraintes appliquées.
