摘要：
The objective of this chapter is twofold. First, it provides a general overview of the Eulerian-Lagrangian modelling approach to the numerical simulation of turbulent dispersed flows in the point-particle limit. Second it reviews the phenomenology of particle deposition and resuspension in wall-bounded turbulence as brought to light by Eulerian-Lagrangian studies over the last two decades. Specific interest is devoted to the case of inertial particles, which are ubiquitous in environmental and industrial flow-systems. Effects due to particle shape on deposition and resuspension mechanisms, as well as on numerical modelling are also addressed.
