We analyzed an oscillating granular layer as a fluid. Our study reveals that granular viscosity controls pattern formation wavelengths, matching experimental data.

Area of Science:

Fluid dynamics
Granular physics
Non-Newtonian fluids

Background:

Granular materials exhibit complex behaviors under oscillation.
Understanding pattern formation in granular layers is crucial for various applications.
The rheology of granular materials, particularly viscosity, is not fully understood.

Purpose of the Study:

To perform a linear stability analysis of an oscillating granular layer.
To determine the granular viscosity and most unstable wavelength using experimental critical acceleration.
To investigate the relationship between viscosity and pattern wavelength.

Main Methods:

Treating the granular layer as an isothermal, incompressible fluid with zero surface tension.
Utilizing experimental critical acceleration data as input for theoretical analysis.
