Clusters and coherent voids in particle-laden wake flow

Effect of Particle Clusters on Turbulence Modulations in Liquid Flow Laden with Fine Solid Particles

Studies on particle distributions and interactions between the particles and the liquid turbulence are extremely significant and can help to improve efficiency of industrial processes and final product quality. In this paper, the particle distribution and the particle–turbulence interaction in the solid–liquid flow were investigated in detail by a numerical method. The governing equations of th...

development of an explicit eulerian method for treating particle laden turbulent flow in dust collectors

Momentum transfer in a turbulent, particle-laden Couette flow

A point-force model is used to study turbulent momentum transfer in the presence of moderate mass loadings of small (relative to Kolmogorov scales), dense (relative to the carrier phase density) particles. Turbulent Couette flow is simulated via direct numerical simulation, while individual particles are tracked as Lagrangian elements interacting with the carrier phase through a momentum coupli...

Particle-laden flow down a slope in uniform stratification

Lock–release laboratory experiments are performed to examine saline and particleladen flows down a slope into both constant-density and linearly stratified ambients. Both hypopycnal (surface-propagating) currents and hyperpycnal (turbidity) currents are examined, with the focus being upon the influence of ambient stratification on turbidity currents. Measurements are made of the along-slope fro...

Behavior of a particle-laden flow in a spiral channel

Spiral gravity separators are devices used in mineral processing to separate particles based on their specific gravity or size. The spiral geometry allows for the simultaneous application of gravitational and centripetal forces on the particles, which leads to segregation of particles. However, this segregation mechanism is not fundamentally understood, and the spiral separator literatures does...
