Drop Dynamics on the Beads-on-String Structure for Viscoelastic Jets
It is well known that a viscoelastic jet breaks up much more slowly than a Newtonian jet.
Typically, it evolves into the so-called
beads-on-string structure ,
where large drops are connected by thin threads.
The slow breakup process provides the viscoelastic jet sufficient time to
exhibit some new phenomena, including drop migration, drop oscillation, drop
merging and drop draining.
