- TL;DR Summary
- My final year experiment involves vibrating a granular conveyor with the same amplitude at at different frequencies.
My final year experiment involves vibrating a granular conveyor with the same amplitude at at different frequencies. (See picture for experiment set-up).
Between 5-115 Hz, the glass beads bounce erratically. As soon as the frequency hits 120Hz or higher, the beads remain on the surface, and can be seen behaving collectively as a liquid. I am however struggling to find a reason why this is the case.
Any ideas of why the beads behave as a liquid when the frequency is higher?
Cheers!
