    Does a vortex ring have a swirl component?
    The presence of a swirl component of velocity in a vortex ring modifies the relaxation and evolution of numerical Gaussian cores in a manner that is currently unknown. The evolution of Gaussian axisymmetric vortex rings of size 0.2 < Λ < 0.5, with Gaussian swirls of magnitude 0.0 < W < 0.5, is analyzed with reference to the governing equations.

    Do additional swirl numbers affect orifice generated circular vortex rings?
    In the present study, the physical effects of additional swirl, for swirl numbers $S \in [0, 1]$, on orifice generated circular vortex rings have been investigated over their formation process, together with their subsequent further development soon after discharge terminates.

    What is peeling off in a vortex ring with swirl?
    Immediately after the formation of a vortex ring with swirl, a columnar strong vortex along the symmetric axis is observed in all cases of the present experiment. Then the characteristic fluid discharging from a vortex ring with swirl referred to as “peeling off” appears.

    What causes large-scale vortex structures in turbulent flows confined by impenetrable surfaces?
    Large-scale vortex structures in the turbulent flows confined by impenetrable surfaces may be created as a result of a sudden change in the value and direction of the flow velocity, upon a change in the geometry of the flow section of channels, if a separation or a turn of the flow occurs, and in other cases.

    How is a vortex ring formed?
    The amount of volume and enstrophy from the discharged fluid delivered to the ring structure is proportional to the duration of the discharge. In a controlled environment, the formation process that produces a vortex ring can be quantified by a simple parameter, namely the stroke ratio

    How does azimuthal instability affect a vortex core?
    The azimuthal instability will eventually lead to turbulence and breakdown of the vortex core; before this occurs, the leading primary ring propagates downstream as a coherent structure – which is typically isolated and compact after it detaches from the trailing jet.
