Stirred, not shaken: Physicists gain more particle control

Cornell physicists can now precisely control how particles in viscous liquids swirl, twirl and whirl. Think of coffee and adding cream—and gaining control of the particles in the cream. Understanding this concept could ...

Study on swirls to optimize contacts between fluids

Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about ...

Shearing triggers odd behavior in microscopic particles

(PhysOrg.com) -- Microscopic spheres form strings in surprising alignments when suspended in a viscous fluid and sheared between two plates — a finding that will affect the way scientists think about the properties of ...

Engineer Discovers Why Particles Like Flour Disperse on Liquids

(PhysOrg.com) -- Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. ...
