Ecological extinction explains how turbulence dies

As anyone who has experienced turbulence knows, its onset and departure are abrupt, and how long it lasts seems to be unpredictable. Fast flowing fluids are always turbulent, but at slower speeds the flow transitions to smooth ...

New particle-sorting method breaks speed records

Researchers compare the processing of biological fluid samples with searching for a needle in a haystack—only in this case, the haystack could be diagnostic samples, and the needle might be tumor cells present in just parts-per-million ...

Simulations pinpoint wind turbine vantage points

Putting small and medium-size wind turbines in the wrong place within built environments can cause them to be less effective—or even have no effect at all—according to research from a Murdoch University PhD student.

Research helps to show how turbulence can occur without inertia

(Phys.org) —Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid—in this case, the flow of air over the wings—becomes chaotic and unstable. For more than a century, the field of fluid ...

Sitting still or going hunting: Which works better?

For the kinds of animals that are most familiar to us—ones that are big enough to see—it's a no-brainer: Is it better to sit around and wait for food to come to you, or to move around and find it? Larger animals that ...

Randomness rules in turbulent flows

It seems perfectly natural to expect that two motorists who depart from the same location and follow the same directions will end up at the same destination. But according to a Johns Hopkins University mathematical physicist, ...
