Abstract
In the previous Paper, it was found that the micrestructural theory by Kanetani could be applied to the flow of grains in an inclined open channel.
In this paper, velocity and density distributions in the layer of the grains flowing in the channel were measured by using paddy, whose moisture contents were controlled into 4 steps, and brown and polished rice. Considerations were given to the flowing states of the grains by macroscopic method, and microscopic method using Kanetani's theory. As a result, the flowing states were characterized by the amount of interaction between grains in which grain rotation and shear were taken into account, and by the energy dissipation rate. It was recognized that the two variables had positive correlation with the average gradient of velocity distributions, respectively.
