This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn into the inner tubing. In this way, droplets of cell medium are entrained into the outlet tubing forming a segmented flow of homogeneously mixed droplets. The simulation allows the sizing and spacing of the droplets to be ascertained.
