It is with great pleasure that we present this book to the public. In principle it is about thermodynamics, especially the simulation of thermo?uid systems. In popular opinion, thermodynamics is considered to be highly abstract and di?cult to comprehend with its many symbols. We endeavor to show the reader how simple and beautiful thermodynamics really is. To achieve this simplicity we apply two innovations: Forus,entropyisasubstance-likeconcept,akindofthermalcharge,analogous to the well-known electric charge, and not the abstract and incomprehensible Clausius integral. This is by no means a new idea: apart from Sadi Carnot himself, people such as Callendar (1911), Job (1971), Falk (1976) and Fuchs (1996) all adopt the same point of view. We stress where thermal charge is analogous with electric charge and also point out the di?erences between them. To represent thermal systems we use Bondgraphs (BG), which are admirably suited to this purpose. They allow us to avoid many complex equations with numerous subscripts and superscripts. Of course, literature on BG abounds, including three books by present co-author Prof. Thoma and several other books published by Springer. We use BG more as a means to clarify the nature of physical variables and theiranalogiesinother?eldsratherthanfromtheviewpointofelectronicdata processing. For example, the di?erence between c (speci?c heat at constant v volume)andc (speci?cheatatconstantpressure)iscommontoallmultipo- p Cs; and BG make this very clear.

Free Download Simulation on Hydration of Tricalcium Silicate in Cement Clinker by Dejian Shen , Xin Wang
English | PDF EPUB (True) | 2023 (2024 Edition) | 195 Pages | ISBN : 9819945976 | 55.2 MB
This book is written based on authors’ research on cement hydration during the past decade. It establishes simulation model to evaluate the influence of crystal defects on the dissolution of tricalcium silicate and morphology change of particles and explores the hydration kinetics and microstructure development of tricalcium silicate under the mixed control of dissolution, diffusion, as well as boundary nucleation and growth. It also provides a theoretical basis for regulating the microstructure and performance of cement-based materials. It is designed as a reference work for professionals or practitioners and as a textbook for undergraduates or postgraduates. This book provides valuable knowledge and useful methods that can be applied in the field of cement hydration.

Free Download Modeling and Simulation in Engineering, 2nd Edition by Camelia Petrescu, Valeriu David
English | PDF | 2023 | 258 Pages | ISBN : 3036582886 | 27 MB
The Special Issue Modeling and Simulation in Engineering, belonging to the section Engineering Mathematics of the Journal Mathematics, publishes original research papers involving advanced simulation and modeling techniques. The present book, "Modeling and Simulation in Engineering 2nd Edition, 2023", contains 13 papers accepted after peer review by recognized specialists in the field. The papers address different topics in engineering that use modeling, optimization as well as experimental and numerical methods. The subject of the papers addresses technical problems such as adaptive contoller design for non-linear systems, simulation of light scattering produced by special paints, estimation of the magnetic field produced by overhead power lines, angle estimation using inertial measurement units, study of multiple transfer phenomena in viscuous fluid flow, optimization of aircraft tail using numerical methods, the study of new types of adjustable speed drives, investigation of nano-fluid flow in different systems, metaheuristic methods applied for maximum power point tracking in photovoltaic systems, as well as theoretical topics such as the use of surrogate models in optimization problems and characterization of structured singular values. It is hoped that the papers selected for thisSpecial Issue will attract a significant audience in the scientific community and will further stimulate research involving modelling and simulation in mathematical physics and in engineering.
