The development of mechatronic and multidomain technological systems requires the dynamic behavior to be simulated before detailed CAD geometry is available. This book presents the fundamental concepts of multiphysics modeling with lumped parameters. The approach adopted in this book, based on examples, is to start from the physical concepts, move on to the models and their numerical implementation, and finish with their analysis. With this practical problem-solving approach, the reader will gain a deep understanding of multiphysics modeling of mechatronic or technological systems – mixing mechanical power transmissions, electrical circuits, heat transfer devices and electromechanical or fluid power actuators. Most of the book's examples are made using Modelica platforms, but they can easily be implemented in other 0D/1D multidomain physical system simulation environments such as Amesim, Simulink/Simscape, VHDL-AMS and so on.

Modelling of Nuclear Reactor Multiphysics: From Local Balance Equations to Macroscopic Models in Neutronics and Thermal-Hydraulics is an accessible guide to the advanced methods used to model nuclear reactor systems. The book addresses the frontier discipline of neutronic/thermal-hydraulic modelling of nuclear reactor cores, presenting the main techniques in a generic manner and for practical reactor calculations. The modelling of nuclear reactor systems is one of the most challenging tasks in complex system modelling, due to the many different scales and intertwined physical phenomena involved. The nuclear industry as well as the research institutes and universities heavily rely on the use of complex numerical codes. All the commercial codes are based on using different numerical tools for resolving the various physical fields, and to some extent the different scales, whereas the latest research platforms attempt to adopt a more integrated approach in resolving multiple scales and fields of physics. The book presents the main algorithms used in such codes for neutronic and thermal-hydraulic modelling, providing the details of the underlying methods, together with their assumptions and limitations. Because of the rapidly expanding use of coupled calculations for performing safety analyses, the analysists should be equally knowledgeable in all fields (i.e. neutron transport, fluid dynamics, heat transfer). The first chapter introduces the book’s subject matter and explains how to use its digital resources and interactive features. The following chapter derives the governing equations for neutron transport, fluid transport, and heat transfer, so that readers not familiar with any of these fields can comprehend the book without difficulty. The book thereafter examines the peculiarities of nuclear reactor systems and provides an overview of the relevant modelling strategies. Computational methods for neutron transport, first at the cell and assembly levels, then at the core level, and for one-/two-phase flow transport and heat transfer are treated in depth in respective chapters. The coupling between neutron transport solvers and thermal-hydraulic solvers for coarse mesh macroscopic models is given particular attention in a dedicated chapter. The final chapter summarizes the main techniques presented in the book and their interrelation, then explores beyond state-of-the-art modelling techniques relying on more integrated approaches. Covers neutron transport, fluid dynamics, and heat transfer, and their interdependence, in one reference Analyses the emerging area of multi-physics and multi-scale reactor modelling Contains 71 short videos explaining the key concepts and 77 interactive quizzes allowing the readers to test their understanding

Physics-based computational modeling is an essential aspect of research and development of new photovoltaic (PV) technologies. For example, PV modeling allows us to improve our understanding of device physics, evaluate the potential of new device architectures prior to experimentation, and predict the energy production of PV systems. This dissertation describes the development of improvements to PV modeling at both the device and system levels, as well as the application of these models to obtain new insights into device physics and PV system performance.The first half of this thesis focuses on solar cell modeling using the drift-diffusion approach. Investigations into numerical instabilities of a drift-diffusion model for bilayer organic solar cells are described, and techniques for improving convergence behavior are presented. The drift-diffusion approach is then adapted for planar perovskite solar cells, validated against literature results, and utilized to understand a new experimental result involving the impact of ultrathin fullerene layers on device performance. The second half of this thesis expands our modeling to PV systems. Here, we focus on the effects of temperature and soiling (accumulation of particulate matter on PV module surfaces) on PV system energy production. A general semi-physical model for predicting annual PV soiling losses is developed and integrated with open-source PV performance models and commercial algorithms for PV system cleaning schedule optimization. Additionally, the potentials of machine learning approaches to soiling modeling are discussed and a proof-of-concept is demonstrated. In order to consider the impact of temperature on PV module performance, a coupled thermal-electrical modeling approach is developed by combining temperature-dependent equivalent circuit models with a commercial heat transfer solver. This approach also allows for predicting energy production of PV modules or films installed on irregular surfaces, such as vehicles. Application of the coupled thermal-electrical approach to simulation of residential rooftop and vehicle-integrated PV systems is demonstrated. Overall, this work has resulted in an improved understanding of the numerical methods necessary to ensure stability of drift-diffusion codes, insight into the role of fullerenes in perovskite solar cells, and the development of modeling approaches than can aid in PV system engineering and improve accuracy in PV system energy production forecasting.

This book, edited by Prof. Marta Rencz and Prof Andras Poppe, Budapest University of Technology and Economics, and by Prof. Lorenzo Codecasa, Politecnico di Milano, collects fourteen papers carefully selected for the “thermal and electro-thermal system simulation” Special Issue of Energies. These contributions present the latest results in a currently very “hot” topic in electronics: the thermal and electro-thermal simulation of electronic components and systems. Several papers here proposed have turned out to be extended versions of papers presented at THERMINIC 2019, which was one of the 2019 stages of choice for presenting outstanding contributions on thermal and electro-thermal simulation of electronic systems. The papers proposed to the thermal community in this book deal with modeling and simulation of state-of-the-art applications which are highly critical from the thermal point of view, and around which there is great research activity in both industry and academia. In particular, contributions are proposed on the multi-physics simulation of families of electronic packages, multi-physics advanced modeling in power electronics, multiphysics modeling and simulation of LEDs, batteries and other micro and nano-structures.

The field activated sintering technique (FAST) is a powder consolidation process via the application of pulsed current and pressure. Compared with conventional hot pressing and hot isostatic pressing, FAST has demonstrated a rapid densification process that has the potential to minimize grain growth, which is crucial to achieving excellent physical properties. This work covers the physical phenomena, multi-scale analytical and numerical models, experimental studies, and application of FAST processing. Specifically, a coupled thermal-electric-densification framework for the design and optimization of FAST type processing has been proposed and implemented into a finite element package. A discrete finite element method is also developed to determine the effective thermal conductivity in a particulate system with realistic microstructure. Moreover, FAST simulation of a hip joint replacement is demonstrated.
