A numerical study of the dynamics of a particle settling at moderate Reynolds numbers in a linearly stratified fluid
In this paper, the transient settling dynamics of a spherical particle sedimenting in a linearly stratified fluid is investigated by performing fully resolved direct numerical simulations. The settling behaviour is quantified for different values of Reynolds, Froude and Prandtl numbers. It is demonstrated that the transient settling dynamics is correlated to the induced Lagrangian drift of flow...

متن کاملInterplay of particle shape and suspension properties: a study of cube-like particles.
With advances in anisotropic particle synthesis, particle shape is now a feasible parameter for tuning suspension properties. However, there is a need to determine how these newly synthesized particles affect suspension properties and a need to solve the inverse problem of inferring the particle shape from property measurements. Either way, accurate suspension property predictions are required....
متن کاملInteraction between a pair of particles settling in a stratified fluid.
The anisotropic structure of fluidized suspensions is governed by their microstructures which are in turn determined by the dynamics of particle pair interactions. Here, we present a numerical simulation of particle interaction in linearly stratified fluids. It is shown that unlike homogeneous fluids, stratification results in the attraction of particles settling abreast. The attraction between...
متن کاملMotion of a rod-like particle between parallel walls with application to suspension rheology
e study the dynamics of elongated axisymmetric particles undergoing shear flow between two arallel planar walls, under creeping-flow conditions. Particles are modeled as linear chains of ouching spheres and it is assumed that walls are separated by a distance comparable to particle ength. The hydrodynamic interactions of the chains with the walls are evaluated using our artesian-representation ...
