Contact forces move a particle along an acoustically excited surface: Case of permanent contact

Vladislav Aleshin, Marina Terzi, Jules Ghesquière

It is known that solid particles can move along vibrating surfaces due to the action of oscillating contact forces. The effect is used for sorting or transporting particles (granular mixtures or powders) in food and pharmaceutical industries. Future applications can include actuating micro-devices…
