an organic liquid as W∕O. For W∕O emulsions, water is considered the dispersed
or internal phase, and oil is the continuous or external phase, and conversely for
the O∕W type. Multiple emulsions such as O∕W∕O or W∕O∕W emulsions are also
present in some cases.

2.2.1. Drop size distribution

A population of emulsions is described by emulsion drop size distribution.
The corresponding drop size distribution is a statistical inventory of the
disaggregation of the dispersed phase. Drop size distribution can be expressed
as frequency distribution curves or cumulative curves.

Among various drop size distributions, log-normal distribution function
describes well drop sizes in emulsions ^[3]. Studies on solid grinding ^[4] and
emulsification with turbulent stirring ^[5] show that breakup sequences of drops lead
to such distribution.

Here d is the drop diameter, d_g is the geometric mean drop size and σ_g is the
geometric standard deviation of the distribution.

In some other cases, lognormal distribution is not observed. The drop size
