Granular Convection and the Brazil Nut Effect
Application ID: 144401
Formally known as size separation in vibrated granular materials, the Brazil nut effect (BNE) (and sometimes the Muesli effect) is a phenomenon that causes large grains to separate from small ones and rise to the top of a granular bed under vibrations. This phenomenon can be studied using the power of numerical methods and the discrete element method.
Two models that use the Granular Flow interface are included in this asset to demonstrate the Brazil Nut effect and help visualize some of the processes including percolation and granular convection that strongly influence granular flows under vibration.
