Abstract
A water-fine particle suspension with a uniform initial temperature and concentration in a rectangular cell was heated from a vertical wall and cooled from the opposing vertical wall. The dispersed particles had a distribution in size. In this natural convection, many layers separated by almost-horizontal sharp interfaces were observed. In the beginning the many layers appear, and each interface of the layers falls gradually with a constant velocity, and finally all layers vanish. To make this phenomenon clear, concentrations and mean diameters of the particles in each layer and temperature distributions were measured. Moreover natural convection of the other suspension with the particles which had a narrow size distribution was also investigated.
