Abstract
A numerical model for the natural convection phenomena of the suspension accompanied by particle sedimentation was constructed. In this analysis, particle size distribution can be taken into consideration by distributing virtual particles and tracking each particle. This natural convection was divided into two convection layers. One layer hardly contains particles and the other contains particles. This phenomenon was explained by the numerical model. The mean Nusselt number of the natural convection of the suspension was compared with that of water. Inhibitive effect of the heat transfer by particles was obtained with the same tendency as the experiment.
