I will present two intriguing examples of such flows where, firstly, oscillations in the shape of propagating bubbles are induced by a simple change in tube geometry, and secondly, flexible vessel boundaries that enable streamwise variations of the channel depth suppress viscous fingering instability.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Ch2 class=\u0022mainTitle\u0022\u003EBubble instabilities in constricted geometries\u003C\/h2\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Bubble instabilities in constricted geometries"}],"uid":"27664","created_gmt":"2012-11-12 12:12:15","changed_gmt":"2016-10-08 02:01:17","author":"Alison Morain","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-11-28T14:00:00-05:00","event_time_end":"2012-11-28T15:00:00-05:00","event_time_end_last":"2012-11-28T15:00:00-05:00","gmt_time_start":"2012-11-28 19:00:00","gmt_time_end":"2012-11-28 20:00:00","gmt_time_end_last":"2012-11-28 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.physics.gatech.edu\/seminars-colloquia\/series\/nonlinear-science-and-mathematical-physics\/anne-juel-20121128","title":"http:\/\/www.physics.gatech.edu\/seminars-colloquia\/series\/nonlinear-science-a..."},{"url":"http:\/\/www.manchester.ac.uk\/research\/anne.juel\/","title":"http:\/\/www.manchester.ac.uk\/research\/anne.juel\/"}],"groups":[{"id":"126011","name":"School of Physics"}],"categories":[],"keywords":[{"id":"49861","name":"Bubble instabilities in constricted geometries"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:alison.morain@physics.gatech.edu\u0022\u003Ealison.morain@physics.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
