The book “Auto oscillations in liquid centrifugal nozzles” by Vladimir Zhdanov is a unique study that immerses the reader in the world of complex physical processes occurring in liquid systems. This edition will be especially interesting for those who are fond of mechanics, hydrodynamics and engineering sciences, as well as students and specialists working in the field of design and operation of nozzles and pumps. In his book, Zhdanov examines the phenomenon of autovibration occurring in centrifugal nozzles, which is one of the most pressing problems in the field of fluid mechanics. The author explains in detail how dynamic processes affect the efficiency of the injectors, and what factors can lead to undesirable fluctuations. It uses mathematical models and physical principles to illustrate the complex interactions between fluid and mechanical components, making the material understandable even to those who are not experts in the art. The book will be useful not only to engineers and researchers, but also to students of technical universities who study mechanical systems and their behavior. It can also attract the attention of researchers dealing with the problems of fluid dynamics, as well as developers of new technologies in the field of pumps and nozzles. Readers interested in modern advances in mechanics and hydrodynamics will find in this edition many useful ideas and practical recommendations. The topics raised in the book cover a wide range of issues: from the foundations of vibration theory to the practical aspects of the design and operation of nozzles. Zhdanov not only describes the theoretical aspects, but also shares the results of his own research, which gives the book special value. His approach to the analysis of auto oscillations allows us to better understand how to minimize the negative consequences associated with these phenomena and improve the efficiency of liquid systems. The author's style is distinguished by clarity and logical presentation, which makes complex concepts more accessible to a wide audience. Zhdanov actively uses graphs, diagrams and examples from practice, which helps the reader to better assimilate the material. His previous work has also been noted for its high level of scientific rigor and practical relevance, which confirms his reputation as an expert in fluid mechanics. The book “Auto fluctuation in liquid centrifugal nozzles” will be interesting not only for professionals, but also for those who just want to expand their knowledge in the field of physics and engineering. This edition can be an excellent addition to the library of any engineer or researcher, as well as a useful tutorial for students. If you are looking for literature that combines theory and practice, and also offers new views on familiar problems, then this book will be a real find for you. Thus, “Auto Fluctuations in Liquid Centrifugal Injectors” is not just a scientific publication, but a deep immersion in the world of fluid dynamics, which can change your idea of the operation of injectors and pumps. Do not miss the opportunity to get acquainted with this fascinating and informative book, which opens new horizons in understanding complex physical processes.
