Cool flames for better engines

A "cool flame" may sound contradictory, but it's an important element of diesel combustion—one that, once properly understood, could enable better engine designs with higher efficiency and fewer emissions.

Researchers compute their way toward cleaner coal plants

When you think of turbulence, you might think of a bumpy plane ride. Turbulence, however, is far more ubiquitous to our lives than just air travel. Ocean waves, smoke from fire, even noise coming from jet engines or wind ...

Solving a physics mystery: Those 'solitons' are really vortex rings

(Phys.org) —The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors ...

Turbulence ahead

Although the wind may blow smoothly onto a wind turbine, it comes out the other end shredded into a complex collage of whorls, large and small. In a wind farm, the turbulent wake generated by the first row of turbines drives ...

Simulations unravel mysteries of 2009 Jupiter impact

(PhysOrg.com) -- During July of 1994, both amateur and professional astronomers were captivated as comet Shoemaker/Levy 9 broke apart and slammed into the atmosphere of Jupiter. While these types of impacts are generally ...
