The three-dimensional revolving flow of a particle-fluid suspension above a plane surface is considered. The flow represents an extension of the classical Bödewadt flow to a two-fluid problem. The governing equations for the two phases are coupled t

ABSTRACT: Axis-symmetric spheroids, such as rod-like and disk-like particles, have been found to orient preferentially in near-wall turbulence by both experiment and numerical simulation. In current work we examined the orientation of inertialess sph

Tandem cylinder flow comprises several different flow regimes. Within the reattachment regime, the development of the gap shear layers is of utmost importance to the flow, but has received little attention so far. Through direct numerical simulations

Inertial spheroids, prolates and oblates, are studied in a decaying Taylor–Green vortex (TGV) flow, wherein the flow gradually evolves from laminar anisotropic large-scale structures to turbulence-like isotropic Kolmogorov-type vortices. Along with

Dispersion and mixing of inertial point particles in the unsteady and three-dimensional wake of a circular cylinder at $Re=200$ are investigated via one-way coupled simulations. The presence of streamwise-oriented vortical braids originating from the

Turbulent channel flow simulation of a shear-thinning fluid is considered – see Arosemena et al. (J. Fluid Mech., vol. 908, 2021, p. A43) – and compared with a Newtonian base case to reveal the effects of the shear-dependent rheology on the near-

We present a detailed study of the turbulent wake behind a quarter-ring curved cylinder at Reynolds number$Re=3900$(based on cylinder diameter and incoming flow velocity), by means of direct numerical simulation. The configuration is referred to as a
