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.

This model example illustrates applications of this type that would nominally be built using the following products:
