A large-scale fluid simulation tracking 100,000 particles as they settle through turbulent water has identified a previously unknown convective mixing effect at the leading edge of the particle cloud.

Add hot water and stir. Those simple instructions capitalize on the well-known principle that stirring a solution can speed up chemical reactions. Researchers in Belgium now show that the opposite is ...

Researchers have recently discovered unusual thermal convection in a uniform mixture of high and low viscosity liquids. They found that concentration fluctuations are enhanced by thermal convection ...
