We compare the results of the simulations in three different cases: inviscid and viscous fluid without transport noise, and inviscid fluid perturbed by transport noise. We find that when the transport noise is modeled by a large number of low-intensity point vortices, a delay in the temporal onset of the instability is present in the non viscous case, which resembles what happens in the viscous case.<\/p>\n\n\n\n<p>Based on joint work with Franco Flandoli and Andrea Papini.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We numerically investigate the effect of transport noise on the Kelvin- Helmholtz instability at the interface of two 2D fluids&hellip;<\/p>\n<p><a class=\"btn btn-dark btn-sm unipi-read-more-link\" href=\"https:\/\/www.dm.unipi.it\/en\/eventi\/tba-15\/\">Read More&#8230;<\/a><\/p>\n","protected":false},"author":105,"featured_media":0,"template":"","tags":[],"unipievents_taxonomy":[],"class_list":["post-8803","unipievents","type-unipievents","status-publish","hentry"],"acf":[],"unipievents_startdate":1684245600,"unipievents_enddate":1684249200,"unipievents_place":"Aula Seminari","unipievents_externalid":0,"jetpack_sharing_enabled":true,"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/unipievents\/8803","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/unipievents"}],"about":[{"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/types\/unipievents"}],"author":[{"embeddable":true,"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/users\/105"}],"version-history":[{"count":4,"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/unipievents\/8803\/revisions"}],"predecessor-version":[{"id":9008,"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/unipievents\/8803\/revisions\/9008"}],"wp:attachment":[{"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/media?parent=8803"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/tags?post=8803"},{"taxonomy":"unipievents_taxonomy","embeddable":true,"href":"https:\/\/www.dm.unipi.it\/en\/wp-json\/wp\/v2\/unipievents_taxonomy?post=8803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
