Vertical granular transport in a vibrated U-tube

Abstract:

We present an experimental study of the collective motion of grains inside a U shaped tube undergoing vertical oscillations, and we develop a very simple quantitative model that captures relevant features of the observed behavior. The height difference between the granular columns grows exponentially with time when the system is shaken at sufficiently low frequencies. In vacuum the exponential growth is suppressed. © 2009 Springer-Verlag Berlin Heidelberg.
