    Abstract

    Thermal plumes, formed at the wall of turbulent natural convection cells, play an important role in the re-suspension and dispersion process of inertial particles. For this reason, a good resolution of the region close to the wall is necessary to correctly describe the plumes and, consequently, the particle dynamics. In this work, a Lattice Boltzmann Method (LBM) coupled with Lagrangian particle tracking is used to understand the effects of the filtering action exerted by the grid resolution on particle trajectories. A validation of the numerical method against the work of Kunnen (2009) and Schumacher (2009) is presented and, in this framework, mean and RMS statistics on fluid temperature are considered and analyzed in detail.
