Physicists working in space plasmas have made clever use of the Ulysses spacecraft and the solar minimum to create a massive virtual lab bench to provide a unique test for the science underlying turbulent flows. http://www.physorg.com/news179749839.html Physics Fri, 11 Dec 2009 10:32:09 EST news179749839 A simple redesign of public buses used in hot and dry climates could make passengers more comfortable without the need to use extra fuel running air conditioning, according to a study published in the International Journal of Heavy Vehicle Systems. http://www.physorg.com/news167304970.html Technology Mon, 20 Jul 2009 10:36:40 EST news167304970 New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and uncovered a noise very similar to typical jet engines. These new research findings provide scientists with a more useful probe of the inner workings of volcanic eruptions. Infrasound is sound that is lower in frequency than 20 cycles per second, below the limit of human hearing. http://www.physorg.com/news158419157.html Space & Earth Wed, 08 Apr 2009 14:19:43 EST news158419157 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.
