Stability of the equations for particulate sedimentation

The Physics of Fluids, 1979
The solution of the equations for two-phase flow which models the steady sedimentation of a uniform distribution of particles in a liquid has been shown to be unstable to small perturbations. It is shown that when a diffusivity term (a force on the particles which is linear in the gradient of the particle concentration) with sufficiently large ...

Stabilization of contaminated canal sediments

European Journal of Environmental and Civil Engineering, 2011
ABSTRACT Morocco has valuable assets in marine seaboards and resources. The Mediterranean coasts do more than attracting tourists. That is why it is imperative to reconcile economic development with the quality of the environment. The industrial area in Tangier (Morocco), situated in the south-east area of the city, is a primary source of sediment ...

Origin of Stability in Sedimentation

Physical Review Letters, 2002
Velocity fluctuations and particle concentrations are studied in a liquid fluidized bed to investigate the origin of steady state sedimentation. Both the velocity fluctuations and the particle concentrations are found to strongly depend on height. A flux balance model shows why the bed is stable: velocity fluctuations drive a downward particle flux ...

Effects of estuarine infauna on sediment stability and particle sedimentation

Hydrobiologia, 1990
Secretions produced by the two estuarine benthic invertebrates Corophium volutator and Nereis diversicolor stabilise sediments by increasing their shear strength, and reduce sedimentation of previously resuspended particles. The secretions consist of 1 to 2 μm threads which bind the particles together. They are used by both species in the production of
