Particles Favor Chaos Over Calm | Physical Review Focus

Researchers have simultaneously observed the flow of both the liquid
and solid components of a colloid–a fluid-particle mix akin to blood
or contaminated ground water. The team used an MRI-like imaging system
and found a surprise: even in slowly flowing, dilute colloids, the
particles refuse to remain on purely parallel paths, like calm drivers
on a highway. Instead, they change lanes erratically, as the
researchers report in the 14 December Physical Review Letters. The new insights should improve researchers’ understanding of flows in many kinds of colloids in biology and industry. [Read more ….]
