Generalized Boltzmann Physical Kinetics

The Boltzmann equation (BE) is the classical basis of the transport processes description in plasma, neutral gases, liquids and physics of solid state. But the BE has many shortcomings, for example, the BE is valid only for particles which can be considered as material points, and the appearance of cross-sections in the collision integral is one of the contradictions of the Boltzmann kinetic theory. In other words the BE is not valid in the scale connected with the time of collision. The theory delivered in this book is based on the generalized Boltzmann equation (GBE). The following is realized in the book: The fundamental fact is shown that the introduction of a third scale, which describes the distribution function variations on a time scale of the order of the collision time, leads to a single order terms in the BE prior to the Bogolyubov-chain-decoupling approximations, and to terms proportional to the mean time between collisions after these approximations. It follows that the BE requires a radical modification – which is exactly, what the GBE provides. Many applications of the generalized Boltzmann kinetic theory are considered including transport processes in neutral and ionized gases and liquids. Applications correspond to different areas of physics: acoustics of rarefied gases, strict theory of turbulent flows, Landau damping in plasma and so on.PrefaceHistorical introduction and the problem formulationChapter 1.
