Beads-on-String Structure of Viscoelastic Filaments

Application ID: 89781


This example applies an Oldroyd-B fluid to model the thinning of a viscoelastic filament under the action of surface tension. For times smaller than the polymer relaxation time, the filament develops a beads-on-string structure. At times much larger than the relaxation time, the solution consists of almost spherical drops connected by exponentially thinning threads. Both transient regimes compare well with experimental measurements.
