The main topic of the book is rarefied gas dynamics which can be defined as the study of gas flows in which the distance between two subsequent collisions of a molecule (the so-called mean free path) is not negligible in comparison with the length typical for the surrounding structure.rnAs a tool for the study of the dynamics of rarefied gas the so-called Boltzmann equation is used. As a consequence, the theme of this book is mostly reduced to the study of the Boltzmann equation. Two approaches are presented: 1. Theoretical (Chapters 1-4); 2. Applicable (first section of Chapter 4 and Chapters 5-7).
