The book "Modeling of the heat exchanger" edited by T. In. Prokofieva and the group of authors is a unique publication that will become an indispensable assistant for students, graduate students and specialists in the field of thermal energy and heat engineering .. This work not only immerses the reader in the world of complex physical processes, but also offers practical solutions for modeling heat exchange processes, which makes it relevant for engineers and researchers. From the first pages, the book captures attention, offering readers not just theoretical calculations, but also practical examples that illustrate how heat exchangers can be effectively modeled. The authors, having a rich experience in the field of heat exchange and heat engineering, share their knowledge, which allows readers not only to understand the basic concepts, but also to apply them in practice. The book discusses various types of heat exchangers, their design and principles of operation, which makes it useful for a wide range of readers, from students of technical universities to experienced specialists. The topics raised in the book cover both the basic principles of heat transfer and more complex aspects, such as modeling in non-standard operating modes. This allows the reader to better understand how various factors affect the efficiency of heat exchangers and what methods can be used to optimize their operation. The book also touches on the issues of energy saving and efficiency improvement, which in modern conditions becomes especially relevant. "Modeling of heat exchanger" will be interesting not only for those who study or work in the field of thermal power engineering, but also for those who want to expand their knowledge in related fields, such as mechanics, physics and engineering. The book can be an excellent addition to educational materials for students and teachers, as well as a useful resource for researchers engaged in the development of new technologies in the field of heat exchange. The style of the authors is distinguished by clarity and accessibility of the presentation, which allows even complex concepts to be presented in an understandable form. Each section of the book is provided with illustrations and examples, which makes the material more visual and easily digestible. This is particularly important for technical literature, where visualization plays a key role in understanding. The book “Modeling of the heat exchanger” is part of a wider series of publications devoted to modern technologies in the field of thermal power engineering. It can be compared to other well-known works, such as Heat Exchange in Engineering Systems or Heat and Exchange, making it an important contribution to the library of any specialist in this field. If you are looking for a book that will help you understand the complex processes of heat exchange and give practical tools for modeling them, then “Modeling a heat exchanger” is exactly what you need. This publication will become a reliable companion in your professional path, opening new horizons in understanding heat exchange processes and their application in real life. Do not miss the opportunity to enrich your knowledge and skills with this unique work!
