Faraday wave instability analog in vibrated gas-fluidized granular particles

Structured bubbling in vibrated gas-fluidized beds of binary granular particles: experiments and simulations

“…5,6 Combined gas flow and vibration in a vibrated gas-fluidized bed is often used to fluidize cohesive particles, and recent studies have demonstrated that combined gas flow and vibration can induce scalable, structured flow patterns in grains, 7 such as structured bubbling, 8 convective cells 9 and surface waves. 10…”
