Welcome to the home of the partially coalescing drop movies
To give you an overview, here is a poster on partial coalescence:

General description (poster in ppt)

This is the basic case of partial coalescence:

Drop of ethanol of reservoir on ethanol (experiment)

Drop of ethanol of reservoir on ethanol (simulation)

Saggy drops can yield satellite drops:

Large drop of hexane on reservoir of hexane (exp)

Large drop of hexane on reservoir of hexane (sim)

in wmv format (sim)

VERY Saggy drops can eject tiny droplets:

Very large drop of hexane on reservoir of hexane (exp)

Very large drop of hexane on reservoir of hexane (sim)

in wmv format (sim)

Pair of drops of different sizes may also partially coalesce:

Two drops of immiscible water-like fluids (sim)

in wmv format (sim)
