(85e) Faraday Wave Patterns in Fluidized Granular Materials: Effects of Combined Vertical and Horizontal Vibration

This study thoroughly explored the complex dynamics and determining the onset mechanisms of Faraday waves within a fluidized granular materials subjected to simultaneous vertical and horizontal vibrations, using two-fluid model (TFM) simulations. Through dimensional analysis, a non-dimensional empirical correlations and regime maps for both wavelength and wave height were established. Intriguingly, it is observed that an increase in vertical vibration frequency results in a reduction in horizontal mixing, while horizontal mixing is amplified by an augmentation in horizontal vibration frequency. Furthermore, it is found that the pace of vertical mixing is heightened and horizontal mixing rates are concurrently diminished by elevating gas flow rates.
