Rotationally induced double dancing drops —Alexander Wray (University of Strathclyde) & Radu Cimpeanu (University of Warwick)

<p>Intricate, time-periodic motion of double-droplet structure formed in a simulation of the Moffatt problem. The work is based on novel thick-flow formulations of low-order models, and their comparisons with direct numerical simulations. This is a computer rendering of this complex motion, designed to try to elucidate the sort of motion usually only decipherable via video. Further details are available at https://doi.org/10.1017/jfm.2020.421.(Simulation results are unaltered.)</p>
