The book “Chemical hydrodynamics”, written by the authors of A.. M. and .. D. Polyanin and Z. D. Zapryanov, is a unique and deep work that immerses the reader in the world of complex processes occurring at the junction of chemistry and hydrodynamics. This publication will be a real discovery for students, graduate students and specialists in the field of chemical engineering, as well as for anyone interested in modern scientific research and practical applications in this field. In "Chemical Hydrodynamics", the authors consider many aspects related to the movement of liquids and gases, as well as their interaction with chemical reactions. The book covers a wide range of topics, ranging from the basics of hydrodynamics to complex models that allow you to predict the behavior of various systems. The reader will be able to learn about how physical and chemical processes are interconnected, and how this knowledge can be applied to solving practical problems in industry. One of the key topics of the book is the study of reactions occurring in streams and the influence of various factors on them, such as temperature, pressure and composition of reagents. The authors explain in detail how these parameters can change the speed of reactions and their output, which is extremely important for optimizing production processes. This information will be especially useful for engineers and scientists working in the field of developing new technologies and improving existing processes. The book is written in accessible language, which makes it suitable not only for professionals, but also for students who are just beginning to get acquainted with this complex but fascinating topic. The authors use many examples and illustrations that help to better understand the material and see its practical application. This makes "Chemical Hydrodynamics" not only a textbook, but also a real reference for anyone who wants to deepen their knowledge in this area. The topics raised in the book are relevant and important for modern society. With the ever-increasing demand for new energy sources and efficient resource processing technologies, knowledge of chemical hydrodynamics is becoming necessary. The book emphasizes the importance of an interdisciplinary approach that combines elements of chemistry, physics, and engineering, making it particularly valuable for researchers and practitioners. The style of the authors is distinguished by clarity and logical presentation, which allows the reader to easily follow the thought and assimilate complex concepts. A. M. Kutepov, A. D. Polyanin and Z. D. Zapryanov are experienced specialists whose work is already known in scientific circles . Their previous publications also address various aspects of chemical engineering and hydrodynamics, making them experts in the field. Whether you are looking for books on chemical engineering, hydrodynamics, or just want to expand your knowledge of the interaction of chemical processes and flows, Chemical Hydrodynamics will be an excellent choice. This publication will not only enrich your scientific outlook, but also help you better understand how to put this knowledge into practice.
