N2 - Over the past years, turbulent convection has been the subject of extensive studies (see e.g. Ahlers et al., 2009; Kunnen et al., 2008; Lohse and Xia, 2010), which attempted to determine the main flow features and the contribution of different parameters to the heat transfer in various geometries, but only few of them focused on Lagrangian statistics. Lagrangian tracking can put some light on the local properties of the flow by gathering information on the temperature and velocity fields along the particle trajectory (Schumacher, 2009; van Aartrijk and Clercx 2008). This, in particular, has direct relevance for many industrial and environmental applications where the fluid heat transfer is modified by the presence and deposition of particles on the walls (e.g. nuclear power plants, petrochemical multiphase reactors, cooling systems for electronic devices, pollutant dispersion in the atmospheric boundary layer, aerosol deposition etc.).
