Abstract: Publisher Summary This chapter examines the classical sedimentation problem in view of the continuum theory of mixture. The mixture theory offers a rigorous axiomatic framework for the dynamics of two-phase flow. This theory for a dilute suspension of small negatively buoyant particles provides a physically sound and intuitively satisfying interpretation of turbulent diffusion. The phenomenon can be identified with a correlation arising from decomposition and averaging applied to the drag interaction term in the momentum balances. The classical sedimentation problem, in which a balance of gravitational settling and diffusive fluxes is posed, is embodied in this theory. This chapter also describes the source of the diffusive flux that balances the gravitational settling flux of negatively buoyant particles in a steady, uniform mean flow.
