Some Aspects of the Asymptotics Leading from Gas-Particles Equations Towards Multiphase Flows Equations.

This paper is devoted to the establishment at the formal level of a scaling leading from gas-particles (also called Eulerian-Lagrangian) models for monodisperse thick sprays towards multiphase flows models (also called Eulerian-Eulerian) including the volume fraction as an unknown. This passage to the limit involves the study of an inelastic collision operator acting on internal energies as well as velocities. [ABSTRACT FROM AUTHOR]
