Multiphysics Simulations in Automotive and Aerospace Applications provides the fundamentals and latest developments on numerical methods for solving multiphysics problems, including fluid-solid interaction, fluid-structure-thermal coupling, electromagnetic-fluid-solid coupling, vibro and aeroacoustics. Chapters describe the different algorithms and numerical methods used for solving coupled problems using implicit or explicit coupling problems from industrial or academic applications. Given the book's comprehensive coverage, automotive and aerospace engineers, designers, graduate students and researchers involved in the simulation of practical coupling problems will find the book useful in its approach.�

Provides the fundamentals of numerical methods, along with comprehensive examples for solving coupled problems Features multi-physics methods and available codes, along with what those codes can do Presents examples from industrial and academic applications

Multiphysics Modelling of Fluid-Particulate Systems provides an explanation of how to model fluid-particulate systems using Eulerian and Lagrangian methods. The computational cost and relative merits of the different methods are compared, with recommendations on where and how to apply them provided. The science underlying the fluid-particulate phenomena involves computational fluid dynamics (for liquids and gases), computational particle dynamics (solids), and mass and heat transfer. In order to simulate these systems, it is essential to model the interactions between phases and the fluids and particles themselves. This book details instructions for several numerical methods of dealing with this complex problem.

This book is essential reading for researchers from all backgrounds interested in multiphase flows or fluid-solid modeling, as well as engineers working on related problems in chemical engineering, food science, process engineering, geophysics or metallurgical processing.

Provides detailed coverage of Resolved and Unresolved Computational Fluid Dynamics - Discrete Element Method (CFD-DEM), Smoothed Particle Hydrodynamics, and their various attributes Gives an excellent summary of a range of simulation techniques and provides numerical examples Starts with a broad introduction to fluid-particulate systems to help readers from a range of disciplines grasp fundamental principles

Multiphysics of Wind Turbines in Extreme Loading Conditions addresses the extreme transient loading of wind turbines through a multiphysics modeling approach, notably by considering the dynamic effects and the nonlinearities of the physics involved in such situations. The book forms the basis for understanding multiphysic numerical simulations conducted on onshore and offshore wind turbines and subjected to extreme loading conditions, including storms, earthquakes, blasts, impacts, and tsunamis. The multiphysics approaches used in this book are explained in each chapter, with algorithms then turned into numerical codes to attain a realistic picture of the dynamic response in each scenario. With numerical methods and loading data explained, the complexity of potential problems encountered when extreme dynamic loads are discussed, along with loading types and their effects. The book fills a specific niche in wind power, namely extreme transient loading of wind turbine, offering information and industrial practices as wind energy makes it useful to practice engineers, designers, undergraduate and graduate students. Defines best practices for unique scenarios which are not readily available in the wider literature, such as extreme load conditions, earthquake and storm scenarios Includes multi-physics methods and specific applications within the demands of extreme conditions Offers numerical simulations of both onshore and offshore wind turbines in one place

Finite element analysis has become the most popular technique for studying engineering structures in detail. It is particularly useful whenever the complexity of the geometry or of the loading is such that alternative methods are inappropriate. The finite element method is based on the premise that a complex structure can be broken down into finitely many smaller pieces (elements), the behaviour of each of which is known or can be postulated. These elements might then be assembled in some sense to model the behaviour of the structure. Intuitively this premise seems reasonable, but there are many important questions that need to be answered. In order to answer them it is necessary to apply a degree of mathematical rigour to the development of finite element techniques. The approach that will be taken in this book is to develop the fundamental ideas and methodologies based on an intuitive engineering approach, and then to support them with appropriate mathematical proofs where necessary. It will rapidly become clear that the finite element method is an extremely powerful tool for the analysis of structures (and for other field problems), but that the volume of calculations required to solve all but the most trivial of them is such that the assistance of a computer is necessary.As stated above, many questions arise concerning finite element analysis. Some of these questions are associated with the fundamental mathematical formulations, some with numerical solution techniques, and others with the practical application of the method. In order to answer these questions, the engineer/analyst needs to understand both the nature and limitations of the finite element approximation and the fundamental behaviour of the structure. Misapplication of finite element analysis programs is most likely to arise when the analyst is ignorant of engineering phenomena.

Thermoforming Modeling and Simulation: A Multiphysics Approach concentrates on the modeling and optimization of thermoforming, as well as identifying the structural behavior of thermoplastics used for thermoforming. The book demonstrates the expertise gained through industrial and academic projects in technical transfer. It also illustrates the research and development skills in experimental and numerical modeling of thermoforming. The problem of identifying laws of behavior from experimental data (rheological or mechanical tests in large deformations), using algorithms such as neural networks, is also addressed.Through its multiphysics content, this book is helpful for researchers, teachers and industrialists interested in new advances in thermoforming (characterization of materials, modeling and optimization).
