'Mayonnaise' shows extreme behaviour in turbulent flow
When water and oil form an emulsion inside a strong turbulent flow, this emulsion consists of either water-in-oil droplets or oil-in-water droplets. The turning point between these two is spectacular, researchers of the University of Twente now show: it can make a difference of liquid friction of a factor six. The size of the droplets changes equally fast. This effect may have consequences for the transport of oil or nutrients. The paper, informally already known as ‘the mayonnaise paper’ is in Physical Review Letters and highlighted as an ‘Editor’s suggestion’.
