Liquid jets and bouncing balls combine for surprising results
A new study published in the American Institute of Physics' (AIP) journal Physics of Fluids reveals that the normal rebounding of a ball changes when it is partially filled with a liquid. Unlike an empty sphere or a soli ...

Turbulent flows in 2D can be calculated in new model
Turbulent flows have challenged researchers for centuries. It is impossible to predict chaotic weather more than a week in advance. Wind resistance on a plane or a car cannot be calculated precisely, since ...

Going with the flow
Scientists who study tissue engineering and test new drugs often need to sort, rotate, move, and otherwise manipulate individual cells. They can do this by prodding the cells into place with a mechanical probe or coaxing ...

Wind concentrates pollutants with unexpected order in an urban environment
Cities – with their concrete canyons, isolated greenery, and congested traffic – create seemingly chaotic and often powerful wind patterns known as urban flows. Carried on these winds are a variety of environmental hazards, ...

Engineers model the threat of avalanches
(Phys.org) -- Snow avalanches, a real threat in countries from Switzerland to Afghanistan, are fundamentally a physics problem: What are the physical laws that govern how they start, grow and move, and can theoretical modeling ...

Sound increases the efficiency of boiling
Scientists at the Georgia Institute of Technology achieved a 17-percent increase in boiling efficiency by using an acoustic field to enhance heat transfer. The acoustic field does this by efficiently removing vapor bubbles ...
