Download or read book Fluid Flow and Heat Transfer in Porous Media Manufactured by a Space Holder Method written by Xianke Lu and published by Springer Nature. This book was released on 2020-08-27 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the effects of the material, porosity, pore size and pore shape on flow behaviour and heat transfer in microscale porous media manufactured using a space holder method. It also describes a novel approach to studying flow behaviour in non-transparent materials such as porous metals via flow visualization in transparent media that mimic the porous structure. The book employs a combination of microparticle image velocimetry – a modern, advanced technique – and pressure drop measurement – a more traditional method – that makes the mechanistic study of several phenomena possible. It covers the identification of various flow regimes and their boundaries, velocity profiles on the microscale, the heat transfer coefficient under forced convection, and the correlation between flow behaviour on the pore scale and the convective heat transfer performance of the porous media. Understanding the fundamentals of porous flow, especially on the microscale, is critical for applications of porous media in heat exchangers, catalytic convertors, chemical reactors, filtration and oil extraction. Accordingly, this book offers a valuable resource for all researchers, graduate students and engineers working in the areas of porous flow and porous materials.

Available in PDF, EPUB and Kindle. Book excerpt: MANOGHARAN, GUHA PRASANNA. Analysis of Non-Stochastic Lattice Structure Design for Heat Exchanger Applications. (Under the directions of Dr. Ola Harrysson and Dr. Denis Cormier.) Non-stochastic lattice structures are cellular solids with periodically repeating array of cells formed by interconnected struts. Conventional manufacturing limits cellular solid structures to stochastic foams and honeycombs. The recent advancement of Solid Freeform Fabrication (SFF) enables the manufacturing of spatially controlled non-stochastic cellular solids engineered for the requirements of a particular application. Recent developments led to the application of metal cellular solids for air heating applications. This research proposes to optimize the cellular solid structure design for efficient heat transfer with minimum fluidic pressure loss. The novel concept is to design cellular solids with thicker struts in the direction along the fluid flow and thinner struts perpendicular to the flow with appropriate current supply for optimum performance. The model analyzed has a resistive cellular solid at a fixed temperature. The geometries examined include hexagonal lattice and rhombic dodecahedron. The heat transfer can be enhanced by thicker struts in the core of the structures and subsequently, by increasing the current across the cells. With corresponding experimental validation, the analysis indicates that by varying the cell length at the entry and exit along the flow direction, pressure loss can be significantly reduced. The pressure loss can be minimized by thinner struts in the entry and exit of the cellular solid. The study indicates that there is no significant effect of the angle between the edges on the performance of the system in the length scale considered.

Download or read book On the Electro Chemo Mechanical Coupling in Solid State Batteries and its Impact on Morphological Interface Stability written by Ganser, Markus and published by KIT Scientific Publishing. This book was released on 2021-03-09 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid state batteries with a lithium metal electrode are considered the next generation of high energy battery technology. Unfortunately, lithium metal is prone to harmful protrusion or dendrite growth which causes dangerous cell failure. Within this work the problem of protrusion growth is tackled by deriving a novel electro-chemo-mechanical theory tailored for binary solid state batteries which is then used to discuss the impact of mechanics on interface stability by numerical studies.
Download or read book Cellular Solids written by Lorna J. Gibson and published by Cambridge University Press. This book was released on 1997 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and acoustic properties of cellular solids. Data for commercially available foams are presented on material property charts; two new case studies show how the charts are used for selection of foams in engineering design. Over 150 references appearing in the literature since the publication of the first edition are cited. The text summarises current understanding of the structure and mechanical behaviour of cellular materials, and the ways in which they can be exploited in engineering design. Cellular solids include engineering honeycombs and foams (which can now be made from polymers, metals, ceramics and composites) as well as natural materials, such as wood, cork and cancellous bone.

Download or read book The Effects of Internal Stress and Lithium Transport on Fracture in Storage Materials in Lithium Ion Batteries written by Klinsmann, Markus and published by KIT Scientific Publishing. This book was released on 2016-03-08 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture of storage particles is considered to be one of the major reasons for capacity fade and increasing power loss in Li-ion batteries. In this work, we tackle the problem by merging a coupled model of mechanical stress and diffusion of Li-ions with a phase field description of an evolving crack. The novel approach allows us to study the evolution of the Li concentration together with the initiation and growth of a crack in an arbitrary geometry and without presuming a specific crack path.

This book was released on 2014-12-04 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Custom built setups were developed to investigate micro samples during quasistatic and cyclic testing in tension, compression and bending. Micro molded CuAl10Ni5Fe4-samples showed similar fatigue behavior compared to macroscopic samples due to both the sample size and microstructure being scaled down with the manufacturing process. Results from cyclic three-point bending tests on micro molded 3Y-TZP suggested that a minimum crack extension is necessary to develop cyclically degradable shielding.
