This paper presents results of a series of experiments on the settling velocity of spheres in twocomponent solid-liquid suspensions. Particular emphasis has been given to the effective values of density and viscosity of the mixture which allows us to describe the settling of the spheres in the mixture using appropriate modifications of the equations valid for the settling of spheres in pure flu...

Microplastic (MP) debris is recognized to be one of the most serious threats marine environments. They are found in all seas and oceanic basins worldwide, even remote areas. This further proof that transport MPs very efficient. In present study, we focus our attention on MPs’ owing Stokes drift generated by sea waves. Recent studies have shown interaction between heavy particles leads unexpecte...

It is essential to have a uniform and calm flow field for a primary settling tank with high performance. In other words reducing the kinetic energy of the flow inside the settling tank can improve significantly the efficiency of these tanks and give opportunity to particles to settle in the settling zone of the tank. So determination of the velocity magnitude in various positions can be a good ...

We explore the properties of turbidity currents down a slope into a stratified saline ambient through highly resolved direct Navier-Stokes simulations, and compare our results to experimental results and analytical scaling arguments. Turbidity currents are buoyancy-driven flows where a denser fluid, charged with suspended particles, propagates through a lighter fluid under the effect of gravity...

Abstract Biophysical cohesion, introduced predominantly by Extracellular Polymeric Substances (EPS) during mineral flocculation in subaqueous environments, plays important role morphodynamics, biogeochemical cycles and ecosystem processes. However, the mechanism of how EPS functioning with cohesive particles affects settling behaviors remain poorly understood. We measure initial rate, floc size...
