Opis

Interface phenomena are most fascinating because of the mixing of different scales and the interference of diverse physical processes. This makes it necessary to use different levels of description: microscopic, kinetic, and gas-dynamical. A unified quasiclassical approach is used to answer practical questions dealing with inelastic gas-surface scattering, the kinetics of adsorption layers, the evolution of inhomogeneities and defects at the surface, the Knudsen layer, the development of boundary conditions on the kinetic and gas-dynamical levels, the determination of exchange and slip coefficients, and so on.

O autorze

Applications are taken from the aerodynamics and gas-dynamics of hypersonic flows, the aerothermochemistry of flying vehicles, thin-film growing technologies, biology, and ecology. The book's four parts discuss molecule scattering, adsorption kinetics, some pheonomenological models of thin-film growth and finally the kinetic boundary conditions and inverse scattering problem.
