This book is the first monograph providing an introduction to and an overview of numerical methods for the simulation of two-phase incompressible flows. The Navier-Stokes equations describing the fluid dynamics are examined in combination with models for mass and surfactant transport. The book pursues a comprehensive approach: important modeling issues are treated, appropriate weak formulations are derived, level set and finite element discretization techniques are analyzed, efficient iterative solvers are investigated, implementational aspects are considered and the results of numerical experiments are presented. The book is aimed at M Sc and PhD students and other researchers in the fields of Numerical Analysis and Computational Engineering Science interested in the numerical treatment of two-phase incompressible flows.

Transport Processes at Fluidic Interfaces

There are several physico-chemical processes that determine the behavior of multiphase fluid systems – e.g., the fluid dynamics in the different phases and the dynamics of the interface(s), mass transport between the fluids, adsorption effects at the interface, and transport of surfactants on the interface – and result in heterogeneous interface properties. In general, these processes are strongly coupled and local properties of the interface play a crucial role. A thorough understanding of the behavior of such complex flow problems must be based on physically sound mathematical models, which especially account for the local processes at the interface. This book presents recent findings on the rigorous derivation and mathematical analysis of such models and on the development of numerical methods for direct numerical simulations. Validation results are based on specifically designed experiments using high-resolution experimental techniques. A special feature of this book is its focus on an interdisciplinary research approach combining Applied Analysis, Numerical Mathematics, Interface Physics and Chemistry, as well as relevant research areas in the Engineering Sciences. The contributions originated from the joint interdisciplinary research projects in the DFG Priority Programme SPP 1506 “Transport Processes at Fluidic Interfaces.”

Isogeometric Analysis is a groundbreaking computational approach that promises the possibility of integrating the finite element method into conventional spline-based CAD design tools. It thus bridges the gap between numerical analysis and geometry, and moreover it allows to tackle new cutting edge applications at the frontiers of research in science and engineering. This proceedings volume contains a selection of outstanding research papers presented at the second International Workshop on Isogeometric Analysis and Applications, held at Annweiler, Germany, in April 2014.

Gitterfreie Berechnungsmethoden kommen aufgrund ihrer Flexibilität in erster Linie bei Problemstellungen mit zeitabhängigen komplexen Geometrien zum Einsatz, da sich dort die Erzeugung, Organisation und Anpassung der Rechengitter überaus schwierig und sehr zeitaufwändig gestaltet. Da in zahlreichen Fällen zur effizienten Lösung solcher Problemstellungen die Eulersche Betrachtungsweise notwendig ist, werden geeignete Verfahren zur Approximation der konvektiven Terme benötigt. Dies stellt für gitterfreie Methoden eine große Herausforderung dar, da zur Approximation lediglich eine Menge von Punkten zur Verfügung steht. Während im Rahmen der gitterbasierten Methoden die Approximation konvektions-dominierender Probleme bereits ausführlich behandelt wurde und viele Verfahren bereitgestellt werden, gibt es im Kontext der gitterfreien Methoden bisher nur wenige Ansätze zur Lösung solcher Probleme. Deshalb werden hier neue Verfahren entwickelt, die eine effiziente Lösung konvektions-dominierender Probleme ermöglichen, wobei der Fokus auf der Lösung inkompressibler Strömungsprobleme liegt.

This book serves as a complete and self-contained introduction tothe principles of Computational Fluid Dynamic (CFD)analysis. It is deliberately short (at approximately 300pages) and can be used as a text for the first part of the courseof applied CFD followed by a software tutorial. The mainobjectives of this non-traditional format are: 1) To introduce andexplain, using simple examples where possible, the principles andmethods of CFD analysis and to demystify the `black box’ of aCFD software tool, and 2) To provide a basic understanding of howCFD problems are set and which factors affect the success andfailure of the analysis. Included in the text are themathematical and physical foundations of CFD, formulation of CFDproblems, basic principles of numerical approximation (grids,consistency, convergence, stability, and order of approximation,etc), methods of discretization with focus on finite difference andfinite volume techniques, methods of solution of transient andsteady state problems, commonly used numerical methods for heattransfer and fluid flows, plus a brief introduction into turbulencemodeling.

"Angewandte Mathematik: Body & Soul" ist ein neuer Grundkurs in der Mathematikausbildung für Studienanfänger in den Naturwissenschaften, der Technik, und der Mathematik, der an der Chalmers Tekniska Högskola in Göteborg entwickelt wurde. Er besteht aus drei Bänden sowie Computer-Software. Das Projekt ist begründet in der Computerrevolution, die ihrerseits völlig neue Möglichkeiten des wissenschaftlichen Rechnens in der Mathematik, den Naturwissenschaften und im Ingenieurwesen eröffnet hat. Es besteht aus einer Synthese der mathematischen Analysis (Soul) mit der numerischen Berechnung (Body) sowie den Anwendungen. Die Bände I-III geben eine moderne Version der Analysis und der linearen Algebra wieder, einschließlich konstruktiver numerischer Techniken und Anwendungen, zugeschnitten auf Anfängerprogramme im Maschinenbau und den Naturwissenschaften. Weitere Bände behandeln Themen wie z.B. dynamische Systeme, Strömungsdynamik, Festkörpermechanik und Elektromagnetismus. Dieser Band entwickelt das Riemann-Integral, um eine Funktion zu einer gegebenen Ableitung zu bestimmen. Darauf aufbauend werden Differentialgleichungen und Anfangswertprobleme mit einer Vielzahl anschaulicher Anwendungen behandelt. Die lineare Algebra wird auf n-dimensionale Räume verallgemeinert, wobei wiederum dem praktischen Umgang und numerischen Lösungstechniken besonderer Platz eingeräumt wird. Die Autoren sind führende Experten im Gebiet des wissenschaftlichen Rechnens und haben schon mehrere erfolgreiche Bücher geschrieben.
