This Open Access book reviews recent theoretical and numerical developments in nonlinear model order reduction in continuum mechanics, being addressed to Master and PhD students, as well as to ...researchers, lecturers and instructors. The aim of the authors is to provide tools for a better understanding and implement reduced order models by using: physics-based models, synthetic data forecast by these models, experimental data and deep learning algorithms. The book involves a survey of key methods of model order reduction applied to model-based engineering and digital twining, by learning linear or nonlinear latent spaces. Projection-based reduced order models are the projection of mechanical equations on a latent space that have been learnt from both synthetic data and experimental data. Various descriptions and representations of structured data for model reduction are presented in the applications and survey chapters. Image-based digital twins are developed in a reduced setting. Reduced order models of as-manufactured components predict the mechanical effects of shape variations. A similar workflow is extended to multiphysics or coupled problems, with high dimensional input fields. Practical techniques are proposed for data augmentation and also for hyper-reduction, which is a key point to speed up projection-based model order reduction of finite element models. The book gives access to python libraries available on gitlab.com, which have been developed as part of the research program FUI-25 MORDICUS funded by the French government. Similarly to deep learning for computer vision, deep learning for model order reduction circumvents the need to design parametric problems prior reducing models. Such an approach is highly relevant for image-base modelling or multiphysics modelling.
Advanced Engineering Thermodynamics, Second Edition is a five-chapter text that covers some basic thermodynamic concepts, including thermodynamic system equilibrium, thermodynamic properties, and ...thermodynamic application to special systems.Chapter 1 introduces the concept of equilibrium, maximum work of thermodynamic systems, development of Gibbs and Helmholtz functions, thermodynamic system equilibrium, and conditions for stability and spontaneous change. Chapter 2 deals with the general thermodynamic relations for systems of constant chemical composition; the development of Maxwell relations; the derivatives of specific heats; coefficients of h, p, T, Clausius-Clapeyron equations; the Joule-Thomson effect; and application of van der Waals gas-inversion curves to liquefaction system. Chapters 3 and 4 describe the thermodynamics of ideal gases, ideal gas mixtures, and gas mixtures with variable composition. These chapters also discuss processes involving dissociation-Lighthill ideal dissociating gas, extension to ionization and real gas effects, and characteristics of "frozen" and equilibrium flows. Chapter 5 surveys the thermodynamics of elastic systems, surface tension, magnetic systems, reversible electrical cell, and fuel cell. This chapter also provides an introduction to irreversible thermodynamics, Onsager reciprocal relation, and the concept of thermoelectricity. This book will prove useful to undergraduate mechanical engineering students and other engineering students taking courses in thermodynamics and fluid mechanics.
