The study of heat and mass transfer is fundamental to a wide array of engineering disciplines, from mechanical and chemical engineering to environmental and energy systems. Over the years, this field has seen significant advancements, spurred by the growing demands for efficient thermal systems, renewable energy solutions, and cutting-edge technologies in material science. This book, Heat and Mass Transfer, is the result of a collaborative effort by experts in various subfields, designed to provide a comprehensive and contemporary resource for students, researchers, and professionals.

The first part of the book introduces the fundamental principles of heat transfer, covering conduction, convection, and radiation. These concepts are presented with a focus on both theoretical understanding and practical application. Our authors have ensured that readers of all levels will gain a strong foundation in the core principles of thermal energy transfer, supplemented with real-world examples and illustrations to clarify complex topics.

The second part of the book delves into mass transfer phenomena, including diffusion, mass convection, and membrane processes. These chapters have been designed to give readers a broad yet detailed understanding of mass transfer, equipping them with the knowledge to tackle real-life engineering problems. Throughout this section, the interplay between heat and mass transfer is emphasized, particularly in multi-phase systems and industrial applications.

In an era where sustainability and energy efficiency are of utmost importance, this book also addresses modern challenges in heat and mass transfer, such as energy storage, advanced heat exchanger designs, and novel materials for thermal systems. With contributions from experts in renewable energy and sustainable technologies, we have ensured that this text is up-to-date with current industry trends and challenges.

This multi-author book is structured to cater to a wide audience. Undergraduate and graduate students will find the foundational sections useful for coursework and exams, while professionals and researchers will benefit from the more advanced discussions on emerging technologies and cutting-edge research. Each chapter is backed by practical case studies, computational methods, and problem sets designed to enhance learning and application.

We would like to extend our gratitude to the authors who contributed their time, knowledge, and research to this book. Their expertise in their respective fields has been crucial in making this a valuable resource for anyone looking to deepen their understanding of heat and mass transfer.
