Researchers at the University of Minnesota have developed a unique new computer model called the Virtual StreamLab, designed to help restore real streams to a healthier state. The Virtual StreamLab, which demonstrates the physics of natural water flows at an unprecedented level of detail and realism, was unveiled for the first time this week at the 2009 American Physical Society Division of Fluid Dynamics meeting in Minneapolis, one of the largest conferences in fluid dynamics with more than 1,500 attendees from around the world. http://www.physorg.com/news178315462.html Physics Tue, 24 Nov 2009 20:20:02 EST news178315462 A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. They will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneapolis Convention Center. http://www.physorg.com/news178114279.html Physics Sun, 22 Nov 2009 12:12:30 EST news178114279 If you keep twisting a straight elastic string, at some moment it starts kinking in a wild way. Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild helical shape, which spoils its performance. This phenomenon concerns scientists exploring fusion power, who use powerful magnetic fields to confine plasma during their experiments. http://www.physorg.com/news176402729.html Physics Mon, 02 Nov 2009 20:20:02 EST news176402729 (PhysOrg.com) -- Researchers at the University of Warwick have found what could be the signal of ideal wave "surfing" conditions for individual particles within the massive turbulent ocean of the solar wind. The discovery could give a new insight into just how energy is dissipated in solar system sized plasmas such as the solar wind and could provide significant clues to scientists developing fusion power which relies on plasmas. http://www.physorg.com/news170947797.html Physics Mon, 31 Aug 2009 14:30:59 EST news170947797 The search for the best observatory site in the world has lead to the discovery of what is thought to be the coldest, driest, calmest place on Earth. No human is thought to have ever been there but it is expected to yield images of the heavens three times sharper than any ever taken from the ground. http://www.physorg.com/news170932769.html Space & Earth Mon, 31 Aug 2009 11:08:09 EST news170932769 (PhysOrg.com) -- Creatures large and small may play an important role in the stirring of ocean waters, according to a study released Wednesday that confirms a theory advanced by Charles Darwin. http://www.physorg.com/news168093166.html Space & Earth Wed, 29 Jul 2009 13:33:21 EST news168093166 Scientists at MIT have figured out a key step toward the design of quantum information networks. The results are reported in the July 20th issue of Physical Review Letters and highlighted in APS's on-line journal Physics. http://www.physorg.com/news167278799.html Physics Mon, 20 Jul 2009 03:20:39 EST news167278799 (PhysOrg.com) -- NASA is funding the development of a prototype system to provide aircraft with updates about severe storms and turbulence as they fly across remote ocean regions. http://www.physorg.com/news166197516.html Space & Earth Tue, 07 Jul 2009 15:30:02 EST news166197516 Pioneering mathematical engineers have discovered for the first time a rigid structure which exists within the centre of turbulence, leading to hope that its chaotic movement could be controlled in the future. http://www.physorg.com/news160727144.html Physics Tue, 05 May 2009 07:26:10 EST news160727144 (PhysOrg.com) -- While radar and other existing systems typically warn aircraft pilots of potential weather hazards during flight, they do not detect all possible atmospheric dangers. http://www.physorg.com/news155326640.html Technology Tue, 03 Mar 2009 18:18:29 EST news155326640 (PhysOrg.com) -- ESA`s Venus Express spacecraft has observed an eerie glow in the night-time atmosphere of Venus. This infrared light comes from nitric oxide and is showing scientists that the atmosphere of Earth`s nearest neighbour is a temperamental place of high winds and turbulence. http://www.physorg.com/news154706058.html Space & Earth Tue, 24 Feb 2009 13:54:52 EST news154706058 Lawrence Livermore National Laboratory has signed an agreement with Siemens Energy Inc. to provide high-resolution atmospheric modeling capabilities to improve the efficiency of wind farm sites, turbine design and wind farm operations. http://www.physorg.com/news154704816.html Technology Tue, 24 Feb 2009 13:34:40 EST news154704816 When a flow reaches a certain speed, things get turbulent: The fluid or the gas no longer flows in an orderly fashion but whirls around wildly. However, in contrast to what researchers assumed until now, this state is not permanent. Scientists from the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany, and the Technical University in Delft, Netherlands, have shown that in pipe flows, all turbulence will disappear with time. The new measurements are significantly more precise than all previous experiments and computer simulations concerned with this question.
