| Research Abstract |
The aggregation process of granules driven by the motion of water-air fronts in the drying process of two-dimensional wet granular systems is experimentally studied. And a model for the collective motion of granular particles induced by an interaction with interface motion is constructed. By the experiment and the numerical simulation, it is found that the model can qualitatively reproduce labyrinthine patterns that are quite similar to those experimentally obtained in the drying process of a water-granule mixture. Moreover, the stick-slip motion of the interfaces and fractal properties are confirmed in our model.
