The book "Numbered modeling of spatial convective processes in the conditions of space flight" by Yaremchuk V. P. It is a unique study that immerses the reader in the world of complex physical phenomena occurring in conditions of weightlessness. This edition will be especially interesting for those who are fond of physics, astronomy, engineering and space technologies, as well as for students and graduate students studying these disciplines. In his book, Yaremchuk examines the key aspects of numerical modeling that are necessary to understand convective processes in space. Convection is one of the main mechanisms of heat and mass transfer, and in space flight it acquires special importance. The author explains in detail how different parameters, such as temperature, pressure, and density, affect the behavior of liquids and gases under microgravity conditions. This knowledge is critical for the development of new technologies related to spaceflight, as well as for ensuring the safety and efficiency of spacecraft. The book not only introduces the reader to the theoretical foundations, but also offers practical examples and models that can be used to explore various scenarios. Yaremchuk shares his observations and conclusions based on many years of experience in the field of numerical modeling and space research. This makes his work not only a scientific but also a practical guide for engineers and researchers working in the field. The topics raised in the book cover a wide range of issues, ranging from the basics of thermodynamics to complex mathematical models. Readers will be able to learn about how numerical methods can be used to predict the behavior of convective flows in space flight, which opens up new horizons for future research and development. The book also touches on important aspects, such as the impact of microgravity on physical processes and the need to adapt existing models to operate in space. This work will be especially useful for undergraduate and graduate students studying aerospace engineering, physics and mathematics, as well as for professionals working in the field of space technology and research. It can be a valuable source of information for those who want to deepen their knowledge of the complex physical processes taking place in space, and how modern technologies help to model them. Yaremchuk's style is clear and accessible, which makes complex concepts understandable even for readers who do not have deep knowledge in the field of physics. His ability to explain complex things in simple language, supported by examples and illustrations, makes the book not only a scientific work, but also a fascinating reading. If you are looking for literature at the intersection of science and practice that will help you better understand how convective processes work in space, then “numerical modeling of spatial convective processes in space flight” will be a real find for you. This book will not only expand your knowledge, but also inspire new ideas and research in the field of space technology.
