    • If the granular packing undergoes ballistic flight it can be shown that for Γ > Γ c ≈ 1.81 the maximum gap would be greater than the amplitude of vibration a. So for Γ > Γ c if s max ′ is small then we can say that the gap is small. If τ K is small and Γ is large we find that the maximum dimensionless gap is given by s max ′ ≃ ( (2 Γ - π ) / Γ ) τ K.

    • It can be shown that within the model of Kroll the fluidization condition (10) always occurs when the effective gravity g ef is still pointing upwards.
