Book excerpt: Nanofluids are a new class of heat transfer fluids engineered by dispersing and stably suspending nanoparticles in traditional heat transfer fluids. Recently they have obtained global attention from the scientific community owing to their unique properties and significant applications in different engineering fields. Nanofluids: Preparation, Applications and Simulation Methods provides a comprehensive review of recent advances in this important research field. Different approaches for preparing some remarkable families of nanofluids such as aluminum oxide-based nanofluids, CuO/Cu-based nanofluids, carbon nanotubes/graphene-based nanofluids, ZnO-based nanofluids, Fe3O4-based nanofluids, and SiO2-based nanofluids are discussed in detail as well as their current and potential applications. Different approaches for numerical, semi-analytical and analytical simulations are also discussed including molecular dynamics, the Lattice Boltzmann method, and spectral methods, as well as advanced analytical techniques such as the Differential Transform Method, the Homotopy Analysis Method, and Optimal Homotopy Analysis. The book will be a valuable reference resource for academic and industrial researchers, materials scientists and engineers, nanotechnologists, and chemists working in the development of nanomaterials and nanofluids for heat transfer in energy and engineering applications. - Covers the synthesis of nanostructures, preparation of nanofluids, different applications and proposed models for fluid mechanics and heat transfer - Presents recent advances on preparation methods, including green chemistry-based methods for preparation of nanomaterials and nanofluids - Includes novel model-based approaches such as molecular dynamics and Lattice Boltzmann methods - Delves into applications in renewable energy technologies and thermal management - Contains a Semi-analytical approach for solving Time-Fractional Navier-Stokes Equation

Download or read book Numerical modeling and simulation of particulate fouling on structured heat transfer surfaces using multiphase Eulerian Lagrangian LES written by Robert Kasper and published by Cuvillier Verlag. This book was released on 2021-04-30 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Durch die gezielte Strukturierung von wärmeübertragenden Oberflächen, wie beispielsweise durch Dellen oder Rippen, kann die örtliche Turbulenz und damit die thermische Durchmischung gesteigert werden. Dies kann die Effizienz von Wärmeübertragern oder Bauteilkühlsystemen erheblich erhöhen. Derartige Oberflächenstrukturrierungen begünstigen jedoch das Partikelfouling, daher die Ablagerung suspendierter Partikel, wie z.B. Sand, Schlamm oder Korrosionsprodukte. Gegenstand dieser Arbeit ist die Entwicklung eines universellen, numerischen CFD-Verfahrens zur Vorhersage des partikulären Foulings auf strukturierten Oberflächen, speziell Dellenoberflächen. Das entwickelte Verfahren basiert auf einer Kombination des Lagrangian-Particle-Trackings zur Beschreibung der dispersen Phase (Foulingpartikel), sowie räumlich und zeitlich aufgelöster Large-Eddy Simulation für die Berechnung der kontinuierlichen Phasen (Trägerfluid). Dieses Vorgehen ermöglicht nicht nur die Auswertung der infolge der Partikelablagerungen verminderten thermo-hydraulischen Effizienz, sondern auch die Untersuchung der Wechselwirkungen zwischen turbulenten Strömungsstrukturen und dem partikulärem Fouling. Dadurch kann gezeigt werden, dass die Verwendung von sphärischen Dellen als Oberflächenstrukturen nicht nur aus thermo-hydraulischer Sicht die optimale Wahl darstellt, sondern auch eine substantielle Verminderung des Partikelfoulings begünstigt. The application of structured heat transfer surfaces, such as dimples or ribs, increase the local turbulence and thus thermal mixing. This can improve the efficiency of heat exchangers or cooling systems significantly. However, structured surfaces are known to promote particulate fouling, hence the unwanted accumulation and deposition of suspended particles (e.g., silt, sludge or iron oxide). The scope of this work is the development of a universal numerical CFD method for the prediction of particulate fouling, especially on dimpled surfaces. The proposed approach is based on a combination of the Lagrangian point-particle tracking for the description of the disperse phase (fouling particles), and spatially and temporally resolved large-eddy simulations for the calculation of the continuous phase (carrier fluid). This approach allows not only the evaluation of the reduced thermo-hydraulic efficiency due to particle deposition, but also the investigation of the interaction between turbulent flow structures and the particulate fouling. It can be shown that the usage of spherical dimples as surface structures is not only the optimal choice from a thermo-hydraulic point of view, but also favors a substantial reduction of particulate fouling.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers state-of-the-art development in microfluidics-enabled soft manufacturing (MESM), ranging from fundamentals to applications. The book addresses the long-standing challenge in the manufacture of simultaneously achieving both precise control over nano-/micro-scale structures and large-scale fabrication of materials for pragmatic use, with microfluidics-enabled soft manufacture to fill the gap between the widely-varied length scales involved. It offers a comprehensive insight into the microfluidic generation of fluid systems as liquid templates, such as droplets, bubbles, jets, emulsions, and foams, which are categorized into individual templates, one-dimensional arrays, and two-/three-dimensional assemblies for the modular fabrication of microparticles, microfibers, and porous materials, respectively. MESM enriches the compositional and structural diversity of engineered materials for well-tailored properties and functionalities, markedly broadening the application horizons across interdisciplinary fields, including engineering, environment, physics, chemistry, biology, and medicine. This book aims to systematize this emerging yet versatile and powerful technology, with the hope of aiding the realization of its full potential. Microfluidics-Enabled Soft Manufacture will be an invaluable reference for graduate students, postgraduates, researchers, and practitioners/professionals working in micro and nanofabrication, materials science, surface science, fluid dynamics, and engineering.
