Kinetic Theory for Binary Granular Mixtures at Low Density

摘要: Many features of granular media can be modelled as a fluid hard spheres with {\em inelastic} collisions. Under rapid flow conditions, the macroscopic behavior grains described through hydrodynamic equations. At low-density, fundamental basis for derivation equations and explicit expressions transport coefficients appearing in them is provided by Boltzmann kinetic theory conveniently modified to account inelastic binary The goal this chapter give an overview recent advances made gases using tools. Some results presented here cover aspects such properties, energy nonequipartition, instabilities, segregation or mixing, non-Newtonian behavior, .... In addition, comparison analytical those obtained from Monte Carlo molecular dynamics simulations also carried out, showing reliability describe flows even strong dissipation.
