Description:
A low-viscosity drop breaking apart inside a viscous fluid is encountered when air bubbles, entrained in thick syrup or honey, rise and break apart. Experiments, simulations, and theory show that the breakup under conditions in which the interior viscosity can be neglected produces an exceptional form of singularity. In contrast to previous studies of drop breakup, universality is violated so that the final shape at breakup retains an imprint of the initial and boundary conditions. A finite interior viscosity, no matter how small, cuts off this form of singularity and produces an unexpectedly long and slender thread. If exterior viscosity is large enough, however, the cutoff does not occur because the minimum drop radius reaches subatomic dimensions first.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doshi, Pankaj -- Cohen, Itai -- Zhang, Wendy W -- Siegel, Michael -- Howell, Peter -- Basaran, Osman A -- Nagel, Sidney R -- New York, N.Y. -- Science. 2003 Nov 14;302(5648):1185-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Chemical Engineering, Purdue University, West Lafayette, IN 47907, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14615531" target="_blank"〉PubMed〈/a〉
