抄録

A water-fine particle suspension with a uniform initial temperature and concentration in a rectangular cell is heated from a center part of the horizontal bottom wall and cooled from the opposite vertical walls which are kept at the initial temperature. Such a transient natural convection is experimentally studied with various temperature differences between the hot and cold walls. Two kinds of particle with different distribution of particle size are used. During sedimentation of particles, the suspension forms layers. In each layer, concentration of particle, mean diameter of particles, and temperature are measured and time-dependent heat transfer coefficient on the hot wall is also measured. Effects of the temperature difference and the particle size distribution on the natural convection with particle sedimentation are clarified.
