| 释义 | vortices plural ofvortexspecializedorliterary Examples of vorticesvortices 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. 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. They relate this question to the formation of vortices in the medium, a phenomenon that cannot be seen in the one-dimensional model. These examples are from corpora and from sources on the web.
