The Δ-model adds a fixed Δ to collision velocities in vibrated granular fluids to enable Enskog kinetic theory predictions of temperature, equation of state, Navier-Stokes coefficients, mixture nonequipartition, and unconditional stability of homogeneous states.

Unjamming in a 3D Granular System: The Micromechanical Role of Friction in Force Distributions and Rheological Properties
DEM simulations of 3D frictional spheres show friction-dependent trends in force distributions, coordination number, and density during unjamming via random particle removal, qualitatively matching prior observations in dense systems despite the different driving mechanism.
