- Drops and jets of liquids that are miscible with the
surrounding bulk liquid are present in many processes from
cleaning surfaces with the aid of liquid soaps to the creation
of biocompatible implants for drug delivery. Although the
interactions of immiscible drops and jets show similarities
to miscible systems, the small, transient interfacial tension
associated with miscible systems create distinct outcomes
such as intricate droplet shapes and breakup resistant jets.
Experiments have been conducted to understand several
basic multiphase flow problems involving miscible liquids.
Using high-speed imaging of the morphological evolution of
the flows, we have been able to show that these processes are
controlled by interfacial tensions. Further multiphase flows
include investigating miscible jets, which allow the creation
of fibers from inelastic materials that are otherwise difficult
to process due to capillary breakup. This work shows
that stabilization from the diminishing interfacial tensions
of the miscible jets allow various elongated morphologies to
