Abstract

Formation of subsatellites at the capillary breakup of viscous liquid jets has been studied. The proposed analy­tical model qualitatively describes subsatellites formation. The obtained patterns for the formation of subsatellites’ nuclei and dynamics of their separation from a jet well agree with the results of numerical modeling.
