{"doi":"10.1017/s0022112098002080","title":"On the persistence of non-axisymmetric vortices \nin inviscid two-dimensional flows","abstract":"<jats:p>Previous research has suggested that isolated, initially non-axisymmetric\n vortices in \ntwo-dimensional flows tend to become axisymmetric, in a coarse-grained\n sense, by \npurely inviscid mechanisms. That research, however, considered only vortices\n with \nbroadly distributed vorticity. In this paper, it is shown that vortices\n with sufficiently \nsteep edge gradients behave in a radically different way; in particular\n they can remain \nnon-axisymmetric, apparently indefinitely. Such vortices, it is argued,\n are more typical \nin inviscid two-dimensional flows than the broadly distributed vortices\n previously \nconsidered, and hence the tendency for vortices to become axisymmetric\n is not \ngeneric to these flows.</jats:p>","journal":"Journal of Fluid Mechanics","year":1998,"id":27808,"datarank":3.773720729627477,"base_score":4.04305126783455,"endowment":4.04305126783455,"self_citation_contribution":0.6064576901751826,"citation_network_contribution":3.1672630394522945,"self_endowment_contribution":0.6064576901751826,"citer_contribution":3.1672630394522945,"corpus_percentile":null,"corpus_rank":null,"citation_count":56,"citer_count":55,"citers_with_citation_signal":47,"citers_with_endowment":47,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":157454,"name":"DAVID G.
