Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates a variational approach to viscous flows with contact line dynamics based on energy-dissipation modeling. The corresponding model is reduced to a thin-film equation and its variational structure is also constructed and discussed. Feasibility of this modeling approach is shown by constructing a numerical scheme in 1D and by computing numerical solutions for the problem of gravity driven droplets. Some implications of the contact line model are highlighted in this setting.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a treatise on the thermodynamic and dynamic properties of thin liquid films at solid surfaces and, in particular, their rupture instabilities. For the quantitative study of these phenomena, polymer thin films (sometimes referred to as “ultrathin”) have proven to be an invaluable experimental model system. What is it that makes thin film instabilities special and interesting? First, thin polymeric films have an important range of applications. An understanding of their instabilities is therefore of practical relevance for the design of such films. The first chapter of the book intends to give a snapshot of current applications, and an outlook on promising future ones. Second, thin liquid films are an interdisciplinary research topic, which leads to a fairly heterogeneous community working on the topic. It justifies attempting to write a text which gives a coherent presentation of the field which researchers across their specialized communities might be interested in. Finally, thin liquid films are an interesting laboratory for a theorist to confront a well-established theory, hydrodynamics, with its limits. Thin films are therefore a field in which a highly fruitful exchange and collaboration exists between experimentalists and theorists. The book stretches from the more concrete to more abstract levels of study: we roughly progress from applications via theory and experiment to rigorous mathematical theory. For an experimental scientist, the book should serve as a reference and guide to what is the current consensus of the theoretical underpinnings of the field of thin film dynamics. Controversial problems on which such a consensus has not yet been reached are clearly indicated in the text, as well as discussed in a final chapter. From a theoretical point of view, the field of dewetting has mainly been treated in a mathematically ‘light’ yet elegant fashion, often making use of scaling arguments. For the untrained researcher, this approach is not always easy to follow. The present book attempts to bridge between the ‘light’ and the ‘rigorous’, always with the ambition to enhance insight and understanding - and to not let go the elegance of the theory.

Book Synopsis Bioinspired Materials and Metamaterials by : Edward Bormashenko
Download or read book Bioinspired Materials and Metamaterials written by Edward Bormashenko and published by CRC Press. This book was released on 2024-08-14 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of bioinspired materials and metamaterials has changed the philosophy of materials engineering and opened new technological possibilities, as they demonstrate properties that are not found in naturally occurring materials. This book examines advances in these emerging materials classes and investigates how their tailor-engineered properties, such as specific surface energy or refraction index, enable the design of devices and ultimately the ability to solve complex societal problems that are, in principle, impossible with traditional materials. The aim of this book is to survey the scientific foundations of the design and properties of bioinspired materials and metamaterials and the way they enter engineering applications. Introduces the physico-chemical foundations, theoretical groundings, and main equations of biomimetic and metamaterials science Describes how to develop and design these advanced materials and their applications Features end-of-chapter problems to help readers apply the principles Surveys achievements including metamaterials cloaking and the negative mass effect Emphasizes ecological aspects of materials science The text is intended for materials engineering students who have completed courses in general physics, chemistry, and calculus, as well as researchers in materials science and engineering.
Book Synopsis Model Hierarchies and Higher-order Discretisation of Time-dependent Thin-film Free Boundary Problems with Dynamic Contact Angle by : Dirk Peschka
Download or read book Model Hierarchies and Higher-order Discretisation of Time-dependent Thin-film Free Boundary Problems with Dynamic Contact Angle written by Dirk Peschka and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a mathematical and numerical framework for thin-film fluid flows over planar surfaces including dynamic contact angles. In particular, we provide algorithmic details and an implementation of higher-order spatial and temporal discretisation of the underlying free boundary problem using the finite element method. The corresponding partial differential equation is based on a thermodynamic consistent energetic variational formulation of the problem using the free energy and viscous dissipation in the bulk, on the surface, and at the moving contact line. Model hierarchies for limits of strong and weak contact line dissipation are established, implemented and studied. We analyze the performance of the numerical algorithm and investigate the impact of the dynamic contact angle on the evolution of two benchmark problems: gravity-driven sliding droplets and the instability of a ridge.
Book Synopsis Dynamics of Driven Contact Lines by : Shomeek Mukhopadhyay
Download or read book Dynamics of Driven Contact Lines written by Shomeek Mukhopadhyay and published by LAP Lambert Academic Publishing. This book was released on 2012-03 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we study the dynamics of thin fluid films and drops, driven by external forces, including gravity and surface tension in a variety of situations. The motion of these fluids are investigated on both hard(silicon) and soft(gel) surfaces. We explore a variety of issues related to the propagation of the fluid front and the contact line through a number of experiments along with numerical simulations whenever possible. This book will appeal to the growing community of soft matter scientists.
