Felix Baumgartner, an Austrian extreme sportsman, said his next goal is to try to break the long-standing record for the highest ever parachute jump, BBC News reported.American Joe Kittinger made history by leaping from a balloon at 102,800ft some 50 years ago and many have sought to repeat the feat over the years but all have failed.Baumgartner now plans to skydive from a balloon sent to at least 120,000 ft. The daredevil is famous for stunts such as jumping off the Petronas Towers.He could...

ST. PAUL, Minn., Dec. 17 /PRNewswire/ -- WindLogics today announced its participation in a University of Minnesota-led consortium selected by the Department of Energy to study and improve wind turbine performance and reliability. The company will work with University researchers to develop and validate an advanced computational framework for high-resolution simulations of wind turbulence and its effect on wind turbine performance. "Understanding the effects of severe weather and wake...
BERKELEY, Calif. and POCATELLO, Idaho, Dec. 7 /PRNewswire/ -- Nordic Windpower announced today that the first three of its two-bladed wind turbines, destined for community and distributed wind energy projects in North and South America, have begun their journey to Rocha, Uruguay. Nordic Windpower marked the event with a ceremony today at its Pocatello, Idaho facility, attended by state and local dignitaries. The company plans to deliver 16 more N1000 wind turbines to community wind...
Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times stronger than in the typical cooking pot. Hot fluids mix turbulently with warm fluids. As the temperature difference between the cold and warm sides increases, the heat transport increases...
Engineers use aerospace approach to design wave energy systemThe ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the need to be tethered to the seafloor.Now, a team of aerospace engineers is applying the principles that keep airplanes aloft to create a new wave-energy system that is durable, extremely efficient, and can be placed anywhere in the ocean, regardless...
CFD visualization used at Wright State University to study the complex flow physics of dragonfly flightMost students caught hanging out in the school parking lot during class might find themselves in a bit of trouble, but for Dr. Haibo Dong's grad students, it's a study requirement.  "They've been out there all morning trying to catch a few dragonflies," he laughs. "We have a high-speed camera in the lab, but don't have any subjects to film. Catching them can be hard because they're so...
ORLANDO, Fla., Nov. 13 /PRNewswire/ Millar Instruments, Inc., developer and manufacturer of Mikro-Tip® pressure transducer catheters and pressure-volume (P-V) systems, and Transonic Systems, Inc., global leader in the design, manufacture and marketing of flow measurement devices, today announce a new distribution partnership. "I am most pleased that these two giants in the field of physiological measurements, Transonic Systems and Millar Instruments, have reached this agreement,"...

The boomerang is a flying tool, made of wood or carbon fiber-reinforced plastic, with a curved shape that is often used as a weapon or for sport. They have also been made of bones and come in many different shapes and sizes depending on their geographic or tribal origins and their intended function. The most commonly recognizable type is the returning boomerang which travels in an elliptical path and returns to its point of origin. The returning boomerang has lopsided wings in order to create...
A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...
Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...
