In this article, the flow of two uniformly rotating immiscible couple stress fluid layers is
examined. In the upper layer, the flow has different velocity u 1⁠, density ρ 1⁠, viscosity ν …

Understanding internal vortex breakdowns (VBs) and their trajectories in sealed cylinders
are important for the scientific and industrial applications with which they are linked …

The paper reports the results of experimental and numerical studies of vortex motion in an
industrial-scale glass bioreactor (volume, 8.5 L; reactor vessel diameter D, 190 mm) filled 50 …

This experimental study reveals a striking nonlinear-physics phenomenon of fundamental
and practical interest—changing conditions at the interface of two swirling immiscible fluids …

An experimental and numerical study of a multicomponent swirl flow of a liquid in a closed
cylinder is carried out for various values of the relative cylinder elongation and the Reynolds …

This experimental study reveals a curious phenomenon—hysteresis in a lab-scale two-liquid
flow. The rotating bottom disk drives a toroidal circulation of water–glycerin solution (lower …

In this paper, the Vogel–Escudier flow is studied at an aspect ratio of 2.5 and a Reynolds
number range of 330–3000. An attempt is made to control the vortex breakdown bubbles …

We report a systematic experimental study of the mean temperature profile $\theta (\delta z)
$ and temperature variance profile $\eta (\delta z) $ across a stable and immiscible liquid …

Looking for an optimal flow shape for culture growth in vortex bioreactors, an intriguing and
impressive structure has been observed that mimics the strong swirling flows in the …

Numerical simulation is performed for a cylinder-bound two-component liquid flow.
Simulation model is based on the method of lattice Boltzmann equations. The collision …
