Die Grundlagen und Methoden, die zur theoretischen Modellierung und zur Analyse von Strömungsvorgängen mit nicht-newtonschen Fluiden erforderlich sind, werden in diesem Lehrbuch vorgestellt. Zunächst werden die kinematischen, die kontinuumsmechanischen und die stofflichen Grundlagen ausführlich erläutert. Die Anwendung des Basiswissens erfolgt exemplarisch anhand ausgewählter Strömungsvorgänge, die maßgeblich von den nichtlinearen Fließeigenschaften, von den Normalspannungsdifferenzen oder vom Gedächtnis der Flüssigkeiten beeinflusst werden. Dabei haben sich die Inhalte, die Schwerpunkte und die Beispiele gegenüber der ersten Auflage wesentlich geändert. Erstmalig in einem deutschsprachigen Lehrbuch werden auch die Grundzüge einer numerischen Strömungssimulation unter Berücksichtigung komplexer rheologischer Stoffmodelle behandelt.

In dieser Arbeit wird die Innenströmung rotordynamischer Komponenten mit Hilfe der Weakly-Compressible-Smoothed-Particle-Hydrodynamics (WCSPH) Methode simuliert. Dabei handelt es sich in der Anwendung um die Berechnung von Gleitlagermodellen, betrachtet unter den Aspekten der Fluiddynamik. Dazu werden verschiedene Varianten der WCSPH verglichen und in Bezug auf die Anwendungen diskutiert. Im Fokus stehen auch die Randbedingungen, deren Modellierung unter Verwendung der WCSPH ein hohes Maß an Forschungspotenzial in sich tragen. Die benötigten theoretischen Grundlagen zur Kontinuumsmechanik und zur Gleitlagertheorie werden nebst der Grundlagen bezüglich der WCSPH beschrieben. Aus den Grundlagen der WCSPH werden verschiedene Varianten entwickelt, wozu auch verschiedene Modellierungen von Randbedingungen gehören, die erläutert werden. Die Randbehandlung nach Ferrand wird unter Betrachtung einer abweichenden Spannungsformulierung um die Volumenviskosität gemäß der Stokesschen Hypothese erweitert. Aus den Bausteinen der WCSPH in Kombination mit den verschiedenen Randbehandlungen werden vier verschiedene Programmabläufe zusammengesetzt und die jeweiligen Formen der Initialisierung erläutert. Die Programmabläufe werden anhand einer druckgetriebenen Kanalströmung und einer Couetteströmung validiert und die Vor- und Nachteile gegenübergestellt. Die zwei qualitativ überlegenen Methoden werden zur Simulation von Gleitlagerströmungen verwendet. Diese sind aufgespalten in eine exzentrische, stationäre Lagerströmung mit einer translatorisch fest im Strömungsgebiet rotierenden Welle und in ein instationäres Gleitlagermodell mit frei beweglicher Welle, deren Position sich aufgrund einer aufgeprägten Lagerlast und der aus dem Fluid auf die Welle wirkenden Kräfte einstellt. Die Bewegung der Welle im Gleitlager und die Strömung des Fluids sind miteinander gekoppelt, sie interagieren miteinander. Zur Simulation des instationären Falls wird ausschließlich der geeignetste Programmablauf verwendet.

Exploring new variations of classical methods as well as recent approaches appearing in the field, Computational Fluid Dynamics demonstrates the extensive use of numerical techniques and mathematical models in fluid mechanics. It presents various numerical methods, including finite volume, finite difference, finite element, spectral, smoothed particle hydrodynamics (SPH), mixed-element-volume, and free surface flow. Taking a unified point of view, the book first introduces the basis of finite volume, weighted residual, and spectral approaches. The contributors present the SPH method, a novel approach of computational fluid dynamics based on the mesh-free technique, and then improve the method using an arbitrary Lagrange Euler (ALE) formalism. They also explain how to improve the accuracy of the mesh-free integration procedure, with special emphasis on the finite volume particle method (FVPM). After describing numerical algorithms for compressible computational fluid dynamics, the text discusses the prediction of turbulent complex flows in environmental and engineering problems. The last chapter explores the modeling and numerical simulation of free surface flows, including future behaviors of glaciers. The diverse applications discussed in this book illustrate the importance of numerical methods in fluid mechanics. With research continually evolving in the field, there is no doubt that new techniques and tools will emerge to offer greater accuracy and speed in solving and analyzing even more fluid flow problems.

The idea of the book is to provide a comprehensive overview of computational physics methods and techniques, that are used for materials modeling on different length and time scales. Each chapter first provides an overview of the physical basic principles which are the basis for the numerical and mathematical modeling on the respective length-scale. The book includes the micro-scale, the meso-scale and the macro-scale. The chapters follow this classification. The book will explain in detail many tricks of the trade of some of the most important methods and techniques that are used to simulate materials on the perspective levels of spatial and temporal resolution. Case studies are occasionally included to further illustrate some methods or theoretical considerations. Example applications for all techniques are provided, some of which are from the author’s own contributions to some of the research areas. Methods are explained, if possible, on the basis of the original publications but also references to standard text books established in the various fields are mentioned.

Through application of the Smoothed Particle Hydrodynamics (SPH) method, this monograph mainly focuses on large deformations and flow failure simulations of geomaterials and movement behavior, which are always involved in geo-disasters. The work covers the theoretical background, numerical techniques, code implementation issues, and many novel and interesting applications. Two-dimensional and three-dimensional SPH models in the framework of both hydrodynamics and solid mechanics are established, with detailed descriptions. The monograph also contains many appealing and practical examples of geo-disaster modeling and analysis, including the fluidized movement of flow-like landslides, lateral spread of liquefied soils, and flow slides in landfills. In the documented SPH simulations, the propagation of geo-disasters is effectively reproduced. Dynamic behaviors of geomaterials during propagation are ascertained, including sliding path, flow velocity, maximum distance reached, and distribution of deposits. In this way, the monograph presents a means for mapping hazardous areas, estimating hazard intensity, and identifying and designing appropriate protective measures.

Most of the Earth''s surface is covered by water. Our everyday lives and activities are affected by water waves in oceans, such as the tsunami that occurred in the Indian Ocean on 26 December 2004. This indicates how important it is for us to fully understand water waves, in particular the very large ones. One way to do so is to perform numerical simulation based on the nonlinear theory. Considerable research advances have been made in this area over the past decade by developing various numerical methods and applying them to emerging problems; however, until now there has been no comprehensive book to reflect these advances. This unique volume aims to bridge this gap. This book contains 18 self-contained chapters written by more than 50 authors from 12 different countries, many of whom are world-leading experts in the field. Each chapter is based mainly on the pioneering work of the authors and their research teams over the past decades.The chapters altogether deal with almost all numerical methods that have so far been employed to simulate nonlinear water waves and cover many important and very interesting applications, such as overturning waves, breaking waves, waves generated by landslides, freak waves, solitary waves, tsunamis, sloshing waves, interaction of extreme waves with beaches, interaction with fixed structures, and interaction with free-response floating structures. Therefore, this book provides a comprehensive overview of the state-of-the-art research and key achievements in numerical modeling of nonlinear water waves, and serves as a unique reference for postgraduates, researchers and senior engineers working in industry.
