Hydrodynamic Transient Tip Streaming

As mentioned in the previous chapter, tip streaming can be categorized into two different classes: transient tip streaming and microdripping/microjetting. This chapter reviews some transient tip streaming flows produced by hydrodynamics means. Specifically, we consider a surfactant-loaded droplet in a linear extensional flow, the viscous entrainment of selective withdrawal, and bubble bursting. The chapter closes by mentioning other examples that have received less attention. We consider both the subcritical steady flow and the onset of tip streaming in a droplet submerged in a linear extensional flow, paying attention to the effect of a surfactant monolayer. We present the same analysis for the viscous entrainment of selective withdrawal. With respect to bubble bursting, we review the major results for simple liquids and summarize recent studies for liquids containing polymers and surfactants.
