A parameter study revealed the dependence of the cavity structure on the governing dimensionless groups. A theoretical description based on the solution to the Rayleigh\u2013Besant problem was developed to describe the evolution of the cavity shape and yields an analytical solution for the pinch-off time and the sphere\u2019s depth at cavity pinch-off.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">See paper&nbsp;<a href=\"http:\/\/math.mit.edu\/~bush\/wordpress\/wp-content\/uploads\/2012\/09\/aristoff-splash.pdf\">Aristoff &amp; Bush, JFM (2009)<\/a>&nbsp;.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":4790,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[],"class_list":["post-3978","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-interfacial-flows","entry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Water impact of small hydrophobic bodies - John W.
