Single bubbles rising in a water\u2013[BMIM][BF\u2084] mixture at 10&nbsp;wt% are compared against pure water: the drag is systematically higher in the mixture and the bubbles deform more, showing lower aspect ratios, while existing drag correlations underestimate the measured values over the whole diameter range. The release mechanism is also shown to affect the terminal velocity and the trajectory well beyond detachment.<\/p>\n\n\n\n<p class=\"pub-links\"><a href=\"https:\/\/www.auriga.polimi.it\/wp-content\/uploads\/publications\/uit-2026-varallo-paper.pdf\">Paper (PDF, 1.1&nbsp;MB)<\/a> \u00b7 <a href=\"https:\/\/www.auriga.polimi.it\/wp-content\/uploads\/publications\/uit-2026-varallo-slides.pdf\">Slides (PDF, 1.4&nbsp;MB)<\/a><\/p>\n<\/div><\/div>\n\n\n\n<p class=\"is-style-back wp-block-paragraph\"><a href=\"https:\/\/www.auriga.polimi.it\/?page_id=14\">\u2190 All publications<\/a><\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>43rd UIT International Heat Transfer Conference \u00b7 Turin, 22\u201324 June 2026 \u00b7 one oral presentation, with the paper and the slides<\/p>\n","protected":false},"author":6,"featured_media":0,"parent":14,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-322","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/pages\/322","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/comments?post=322"}],"version-history":[{"count":0,"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/pages\/322\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/pages\/14"}],"wp:attachment":[{"href":"https:\/\/www.auriga.polimi.it\/index.php\/wp-json\/wp\/v2\/media?parent=322"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
