摘要：
We report experimental results on radial segregation in a 2d rotating drum half-filled by a mixture of small and large disks. This segregation is present both in the intermittent (avalanches) and in the continuous flow regimes. The kinetics of the process are analysed and appear to be very fast. Some results on a first quantitative analysis of the trapping process-which is the basic mechanism of segregation-within the surface flow are presented.
