Príklady vortices

• The waves propagate away and the vortices ultimately reach an equilibrium, which is discussed below.

• However, the approximate elliptical vortices become elongated to an arbitrarily great extent in this limit, whereas the actual solutions do not.

• The vortices decrease in diameter as they travel downstream.

• When the transverse vortices convected downstream, an ejection sequence occurred near the wall.

• In this case, the intense perturbation of the upper boundary favours the generation of downstream patches of vortices travelling with high phase velocity.

• But the results obtained here concerning the non-uniqueness and hysteresis indicate a probable mechanism for the sudden appearance and disappearance of strong localized atmospheric vortices.

• Around these filaments, or vortices, the superconducting properties are partially destroyed.

• This result indicated that the vortex merging process suppressed the activity of the streamwise vortices and made the mixing layer more two-dimensional.

• Upon returning to the stationary frame of reference, these cells are precisely the viscous vortices oscillating to and fro high above the ripples.

• The vorticity is modelled as point vortices, vortex sheets, and finite area vortex regions.

• In these works the waves and vortices were assumed to be uncorrelated.

• The final state comprises two counter-rotating vortices which dissipate.

• Owing to the induced velocity field, the three vortices start to rotate around each other.

• The role of these potentials is to hold down the vortices from moving as a result of mutual interactions.

• We restrict attention to axially symmetric solutions and consider models with and without vortices.
