Structures evoking vortex rings can be discerned in shock-accelerated flows ranging from
astrophysics to inertial confinement fusion. By constructing an analogy between vortex rings …

An experimental study of particle–vortex interactions has been undertaken in suspensions
with volume fractions up to. Time-resolved particle image velocimetry measurements using a …

Vortex ring (VR) structures occur in light or hoarse cough configurations. These instances
consist of short impulses of exhaled air resulting to a self-contained structure that can travel …

The influence of uniform background co-flow on the propulsive characteristics of starting jets
with stroke ratios (length to diameter ratio, L/D) from 1 to 5 and velocity ratios (ratio of co-flow …

Vortex rings can easily be generated in the laboratory or with homemade devices, but they
have also been observed on volcanoes, since the eighteenth century. However, the physical …

An ultrasound-based Lagrangian particle tracking (echo-LPT) method is used to investigate
path-dependent quantities for confined vortex rings in dense suspensions with volume …

Ring vortices are efficient at transporting fluid across long distances. They can be found in
nature in various ways: they propel squids, inject blood in the heart, and entertain dolphins …

We compared steady and pulsatile CFD simulations with 4D Flow MRI in a phantom model
of arterial stenosis and investigated the hemodynamic features distal to the occlusion. With …

An air supply mode based on vortex ring structures was proposed to deliver fresh air for
good indoor air quality. This study focused on the influence of air supply parameters …

Air vortex-ring-based supply mode was proposed to deliver fresh air. The influence of air
supply parameters on the entrainment and mixing of air vortex rings was investigated …
