This book presents the new discovery of the origin of turbulence from Navier-Stokes equations. The fully developed turbulence is found to be composed of singularities of flow field. The mechanisms of flow stability and turbulent transition are described using the energy gradient theory, which states all the flow instability and breakdown resulted from the gradient of the total mechanical energy normal to the flow direction. This approach is universal for flow instability in Newtonian flow and non-Newtonian flow. The theory has been used to solve several problems, such as plane and pipe Poiseuille flows, plane Couette flow, Taylor-Couette flow, flows in straight coaxial annulus, flows in curved pipes and ducts, thermal convection flow, viscoelastic flow, and magnet fluid flow, etc. The theory is in agreement with results from numerical simulations and experiments. The analytical method used in this book is novel and is different from the traditional approaches. This book includes the fundamental basics of flow stability and turbulent transition, the essentials of the energy gradient theory, and the applications of the theory to several practical problems. This book is suitable for researchers and graduate students.

This book gives insight into the ongoing work of the forum on Philosophy, Engineering and Technology (fPET), which brings together philosophers and engineers from all over the world to discuss philosophical issues of engineering across disciplinary boundaries. Drawing on presentations and conversations at the fPET 2020 online conference hosted by the Universidad Técnica Federico Santa María in Chile, the chapters establish connections and describe discoveries that have so far been neglected in the discussions held within the young discipline of philosophy of engineering. This volume appeals to students and researchers in the field, through twenty-four proposals brought forward by leading scholars and emerging voices. Pertinent themes covered are: the broader engagement of engineers in problem-solving beyond the scope of their own profession the exploration of new goals for technology development and the implementation of strategies to reach these goals the need for philosophical content and unique pedagogical approaches to engineering education, digital transformations, artificial intelligence and the ethics of online collaboration in social media critical revisions of fundamental terminology and theoretical modelling of key concepts in engineering design, ethics, innovation and the anthropology of technology.

Fans In a unique approach, this textbook combines the design and construction of centrifugal and axial fans with the problem of their noise generation and its mitigation. Easily applicable methods of fan selection, aerodynamic fan design, and fan noise prediction are compiled, including most of the underlying physical principles. Other features of this book include introductions to numerical and experimental methods, simulation-based optimization techniques for fan design, and psychoacoustic methods for evaluating fan noise. Numerous practical problems illustrate and reinforce the ideas and concepts. Content Fan performance parameters, demand of a plant and fan selection, fan performance characteristics, model laws, flow kinematics, efficiencies – Design methods for centrifugal and axial fans – Mechanisms of fan sound generation, methods for fan sound prediction – Psychoacoustic evaluation of fan noise – Design features of noise reduced fans – Computational fluid dynamics, fan test rigs, simulation-based optimization – Practice problems and solutions. Target group Students of mechanical engineering at colleges and universities Engineers in the industrial fan manufacturing industry, planning engineers for heating, ventilation air conditioning systems and in equipment and plant engineering Author Prof. Dr.-Ing. Thomas Carolus taught fluid mechanics at the Department of Mechanical Engineering at the University of Siegen, Germany, with a focus on fluid machinery. This book is a translation of the original German 4th edition Ventilatoren by Thomas Carolus, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com), but with a subsequent human revision in terms of content. Springer Nature works continuously to further develop tools for the production of books and on the related technologies to support the authors.

This book provides an in-depth understanding of tyre dynamics. In the first three chapters, new concepts are introduced in respect to the classic theory. Analytical results are derived step-by-step to guide the reader through the governing equations of the model. Transient phenomena are explained in a relatively simple way according to the brush theory. The analysis is extended to cover the case of large camber angles, which is often disregarded. The principal mechanisms behind the transient generation of tyre forces and moment are discussed in general terms, and exact solutions to the rolling contact problem are given for simple contact geometries. The last part of the book is dedicated to the approximated theories of transient generation of tyre forces and moment. Two different models, suitable for use in vehicle dynamics applications, are presented and compared.
