Preface

Thermal energy is present in all aspects of our lives. We experience heat transfer daily when, for example, cooking or taking food out of the fridge, using a vehicle, or turning on the heating or air-conditioning system in our office. Sometimes this thermal management is not evident, but it is essential for our comfort and lifestyle. In addition, heat transfer is of vital importance in all electric power plants. Whether some fuel is burned to obtain steam or whether we want to maintain a solar panel temperature to a certain level, proper management of thermal energy is crucial to

Nowadays it is even more important to control thermal transfer perfectly when designing renewable energy systems where every unit of energy requires use or when installing an efficiency measure in a process to prevent thermal

Thermal energy analysis is a complex task that usually requires the use of large theoretical equations and mathematical models that can predict the behaviour of a certain system. Many approaches can be followed to study all these phenomena. Some of them involve experimental developments that include the building of test benches, rigs, and real systems to replicate the process to be studied. Others are computational models that predict the performance of the system and can be used

This book includes a large compilation of those different approaches and serves as an example of how heat transfer problems can be analysed. It is divided into the

I hope this book will help engineers, researchers, and scientists to understand thermal processes better and teach them how to address heat transfer problems. I also hope it serves as an inspiration for the development
