A defining mark of Jupiter, the Great Red Spot, should have disappeared centuries ago, according to prevailing theories. A new model being presented next week provides a possible explanation for why the turbulent red vortex has lasted so long.
NASA's Ames Research Center and NASA's Langley Research Center, in partnership with The Boeing Co., have completed wind tunnel testing of a full-scale Boeing 757 vertical tail model equipped with active flow control technology.
Stingrays have a unique swimming movement that allows them to move through the water with ease. A new study from the University of Buffalo (UB) and Harvard University is examining those movements to design more agile and fuel-efficient unmanned underwater vehicles.
The Lockheed Martin SR-72 'Son of Blackbird' is now in the works, and according to the company, it will reach speeds up to Mach 6.
Splattered bugs on your windshield can be gross to look at and they can even obstruct your view. However, for some, the ordeal can be much more of a problem than just an unsightly nuisance.
Fluid jets are all around us: from inkjet printing, to the “Old Faithful” geyser in Yellowstone National Park, to cosmological jets several thousand light years long.
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...
