Journal Club Air Entrainment by a Viscous Jet Plunging into a Bath
Tak Chan

Details:

When pouring a viscous liquid in a glass or any type of container you often see a lot of bubbles being generated, which is quite bad if you are in the lab and you need a clean-and-free-of-bubbles sample of liquid. These bubbles appear due to the breakage of a thin film of air surrounding the viscous liquid jet. Shing will describe the phenomenon and will give simple scaling arguments to predict the entrainment rates and film thickness.
