Kinetic Theory of Gases
The present text is based on a set of lectures given as part of a post graduate course in fluid mechanics at the Department of Mechanics, KTH School of Engineering Sciences. The topic of kinetic gas theory was chosen as to broaden the students knowledge in the field of fluid mechanics in general. In particular the students should get a new perspective on the contiuum theory approach applied in ...
متن کاملIII. Kinetic Theory of Gases
• Kinetic theory studies the macroscopic properties of large numbers of particles, start ing from their (classical) equations of motion. Thermodynamics describes the equilibrium behavior of macroscopic objects in terms of concepts such as work, heat, and entropy. The phenomenological laws of thermody namics tell us how these quantities are constrained as a system approaches its equilibrium. A...
متن کاملKinetic Equation Model for Self-gravitating Systems
The kinetic theory of a self-gravitating system is considered in the BhatnagerGross-Krook approximation to the kinetic equation. This approach offers a unique and tractable setup for studying the central, collision-dominated region of the system, as well as its almost collisionless outer part. Stationary non-equilibrium states of the system are considered and several different self-similar solu...
متن کاملRelativistic kinetic theory of magnetoplasmas
Recently, an increasing interest in astrophysical as well as laboratory plasmas has been manifested in reference to the existence of relativistic flows, related in turn to the production of intense electric fields in magnetized systems [1]. Such phenomena require their description in the framework of a consistent relativistic kinetic theory, rather than on relativistic MHD equations, subject to...
متن کاملKinetic Integrals in the Kinetic Theory of dissipative gases
The kinetic theory of gases, including Granular Gases, is based on the Boltzmann equation. Many properties of the gas, from the characteristics of the velocity distribution function to the transport coefficients may be expressed in terms of functions of the collision integral which we call kinetic integrals. Although the evaluation of these functions is conceptually straightforward, technically...
