a new energy dissipation theory for jig bed stratification

The Influence of Whitecapping Waves on the Vertical ...

Near the bed (bottom 10% of the water column), the dissipation measurements were either equal to or less than that predicted by walllayer theory. Stratification due to concentration gradients in suspended sediment was identified as the likely cause for these periods of production–dissipation imbalance close to the bed.

Mathematical Modeling of Particle Stratification in Jigs ...

A new modeling approach based on Newtonian mechanics is used to describe the stratification behavior of particles in jig. In this approach,the motion of solid material is treated using the discrete element method (DEM) while the corresponding motion of the liquid is determined by marker and cell (MAC) technique.
