The Science of the total environment·2023

Area of Science:

  • Statistical physics
  • Granular material dynamics

Background:

  • The behavior of shaken granular materials is complex.
  • Previous models predicted Gaussian velocity distributions for driven inelastic Maxwell models.

Purpose of the Study:

  • To re-examine the steady-state velocity distribution in a driven inelastic Maxwell model.
  • To identify discrepancies with prior predictions regarding velocity tails.

Main Methods:

  • Numerical solution of the master equation.
  • Analytical arguments were employed.

Main Results:

  • The study found bilateral exponential velocity tails, P(v) ~ e(-|v|/sqrt[D]).
  • This contradicts previous predictions of Gaussian tails, P(v) ~ e(-av^2).

  • The noise amplitude D was identified as a key parameter.

    • Conclusions:

    • The driven inelastic Maxwell model exhibits exponential velocity tails.
    • This necessitates a revision of previous theoretical predictions for shaken granular systems.
