The textbook "Behavior of Gas Bubbles in Variable Gravitational Fields" offers a comprehensive study of the physicochemical modeling of gas bubble behavior adhering to the surfaces of solid materials in liquids. It describes in detail how these bubbles interact under various conditions, such as during accelerations and in microgravity. The computer-based simulation allows for precise analysis of parameters during changes in gravity and weightlessness. Furthermore, the behavior of the bubbles is examined in relation to the properties of the liquid, such as surface tension and contact angle. The results of these simulations have been validated through experiments conducted aboard a flying laboratory, underscoring the relevance and accuracy of the developed models. This book is aimed at professionals and students in the fields of mathematics and natural sciences who are interested in the dynamics of gas bubbles in variable gravitational fields.
