# On the stability of vortex rings

@article{Widnall1973OnTS, title={On the stability of vortex rings}, author={S. Widnall and J. Sullivan}, journal={Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences}, year={1973}, volume={332}, pages={335 - 353} }

The stability of vortex rings is investigated both theoretically and experimentally. The theoretical analysis considers the stability of the vortex-filament ring of small but finite core size in an inviscid fluid to small sinusoidal displacements of its centreline. The effect of the vorticity distribution within the finite vortex core on the self-induced motion of each element of the vortex filament is calculated on the basis of the results presented previously by Widnall, Bliss & Zalay (1970… Expand
