The sedimentation process of solid particles in a two-dimensional channel with an initially homogeneous, square configuration is numerically investigated at Reynolds numbers up to 10. The Lattice Boltzmann method is used to simulate the hydrodynamic interactions between fluid and particles....
Non-equilibrium mechanism in the transport of inertia-dominated particles was explained in the problem of particle deposition inside a turbulent boundary layer. Due to the finite inertia of particles and mean shearing of the carrier flows, the transport of inertia-dominated particles inside a...
A ‘mixture model’ for the macroscopic motion of a buoyant suspension is formulated in terms of volume averaged velocities in order to ensure well-posedness of the incompressibility constraint. Conservation laws for mixture volume, momentum and the dispersed phase are complemented by a...
The equilibrium Eulerian method is a simple way to determine the velocity field of a disperse system of particles. It avoids solving a partial differential equation for particle velocity, which makes it more efficient than the standard Eulerian–Eulerian method. It captures such essential...
The lift on a particle that is caused by its proximity to a boundary and the equilibrium position of this particle in a linear shear flow have been studied using the lattice Boltzmann method. The shear particle Reynolds numbers examined were in the range 0–18 and the particle to fluid density...
Numerical analysis of the standard continuum description of a dilute dispersed phase as applied to a laminar, particle-laden, mixing layer during its initial evolution has been performed. The flow has been previously analyzed under the framework of linear stability analysis where both the...
Transfer and deposition of inertial particles or droplets in turbulent pipe flow are crucial processes in a number of industrial and environmental applications. In this work, we use direct numerical simulation (DNS) and Lagrangian tracking to study turbulent transfer and deposition of inertial...
