ABSTRACT
Particle-fluid interaction refers to the exchange of properties between phases and is responsible for coupling in dispersed phase flows. The conservation equations for single particles or droplets are introduced. The phenomena responsible for mass, momentum and energy transfer between phases are then presented. The purpose of this chapter is not to provide an extensive review of fluid-particle interaction but to present some of the basic ideas and observations. Reference to books by Clift et al. (1978), Michaelides (2006) and the Multiphase Flow Handbook [Crowe (ed.), 2006] as well as review papers in the literature provide more details.
