3-Dimensional Motion of an Intruder in Brazil Nut Effect

摘要

The purposes of this article were to experimental setup for finding the position of an intruder inside a vibrating granular bed which is the important information for one to understand the mechanism of the Brazil nut effect. However the intruder is difficult to be observed without using some sophisticated methods. And then shown is a simple method to reconstruct the 3-dimensional motion of an intruder inside a vibrating granular bed in annular container case.
