Title: Traveling Faraday Waves in Fluidized Granular Materials using Angled Vibration

Author (Table Talk): Oscar Punch, Columbia University

Abstract:

We present experiments and numerical simulations showing dynamically structured Faraday wave patterns in vibrated gas-fluidized granular materials which more horizontally over time due to presence of vibration acting at an angle. We characterize the velocity of these Faraday waves and explain their mechanism. The presence of traveling Faraday waves decompartmentalizes particle motion in structured fluidized beds, enhancing mixing.
