During slow drainage, granular-fluid systems form complex labyrinth patterns. Pattern scale depends on grain density and system thickness, offering insights into granular flow dynamics.

Area of Science:

  • Physics
  • Fluid Dynamics
  • Materials Science

Background:

  • Granular-fluid systems exhibit complex behaviors during drainage.
  • Pattern formation in confined systems is not fully understood.

Purpose of the Study:

  • Investigate the formation of labyrinthine patterns in 2D granular-fluid systems.
  • Identify factors influencing the characteristic length scale of these patterns.

Main Methods:

  • Simulated slow drainage of a 2D granular-fluid system.
  • Analyzed the competition between capillary forces and frictional stress.
  • Developed an analytical model to predict pattern length scale.

Main Results:

  • A random, labyrinthine pattern emerges during slow drainage.

  • Pattern formation is driven by fluid-air interface instability.
  • The characteristic length scale decreases with increased grain volume fraction.
  • The characteristic length scale increases with system thickness.

    • Conclusions:

    • The study elucidates the mechanism behind labyrinth pattern formation in confined granular-fluid systems.
    • Provides a predictive model for pattern length scale based on system parameters.
    • Offers fundamental insights into granular flow and interface dynamics.
