Dual vortex breakdown in a two-fluid whirlpool [PDF]
Scientific Reports, 2021 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 atmosphere (tornado) and ocean (waterspout).

Shock/Vortex Interaction and Vortex-Breakdown Modes [PDF]
31st Aerospace Sciences Meeting, 1993 Computational simulation and study of shock/vortex interaction and vortex-breakdown modes are considered for bound (internal) and unbound (external) flow domains. The problem is formulated using the unsteady, compressible, full Navier-Stokes (NS) equations which are solved using an implicit, flux-difference splitting, finite-volume scheme.

Microscopic Investigation of Vortex Breakdown in a Dividing T-Junction Flow [PDF]
, 2018 3D-printed microfluidic devices offer new ways to study fluid dynamics. We present the first clear visualization of vortex breakdown in a dividing T-junction flow. By individual control of the inflow and two outflows, we decouple the effects of swirl and

A coaxial vortex ring model for vortex breakdown [PDF]
Physica D: Nonlinear Phenomena, 2008 A simple - yet plausible - model for B-type vortex breakdown flows is postulated; one that is based on the immersion of a pair of slender coaxial vortex rings in a swirling flow of an ideal fluid rotating around the axis of symmetry of the rings. It is shown that this model exhibits in the advection of passive fluid particles (kinematics) just about ...

The role of non-uniqueness in the development of vortex breakdown in tubes [PDF]
, 1992 Numerical solutions of viscous, swirling flows through circular pipes of constant radius and circular pipes with throats have been obtained. Solutions were computed for several values of vortex circulation, Reynolds number and throat/inlet area ratio ...

The role of the stratospheric polar vortex for the austral jet response to greenhouse gas forcing [PDF]
, 2017 Future shifts of the austral midlatitude jet are subject to large uncertainties in climate model projections. Here we show that, in addition to other previously identified sources of inter-model uncertainty, changes in the timing of the stratospheric ...
