Abstract
A method of creating substantially monodisperse droplets comprising supplying a first fluid () and a second immiscible fluid () within a set of channels, the second fluid surrounding the first fluid and filling the channels to form a composite jet. The composite jet passes through an entrance channel () into a wider cavity (), where the first fluid breaks into droplets (), the resulting composite of droplets of the first fluid within the second fluid passing through an exit channel (). The cross sectional area of the exit channel perpendicular to the flow is smaller than the cross sectional area of the cavity and the passage of a droplet of the first fluid out of the cavity via the exit perturbs the composite flow field within the cavity such that the incoming jet of the first fluid is perturbed.
