Another everyday example of Plateau–Rayleigh instability occurs in urination, particularly standing male urination. [9] [10] The stream of urine experiences instability after about 15 cm (6 inches), breaking into droplets, which causes significant splash-back on impacting a surface. By contrast, if the stream contacts a surface while still in ...
The waves can take the form of stripes, close-packed hexagons, or even squares or quasiperiodic patterns. Faraday waves are commonly observed as fine stripes on the surface of wine in a wine glass that is ringing like a bell. Faraday waves also explain the 'fountain' phenomenon on a singing bowl.
This figure represents the evolution of the Rayleigh–Taylor instability from small wavelength perturbations at the interface (a) which grow into the ubiquitous mushroom shaped spikes (fluid structures of heavy into light fluid) and bubbles (fluid structures of light into heavy fluid) (b) and these fluid structures interact due to bubble merging and competition (c) eventually developing into ...
Hydrodynamics simulation of the Rayleigh–Taylor instability [3] Unstable flow structure generated from the collision of two impinging jets.. Fluid instabilities occur in liquids, gases and plasmas, and are often characterized by the shape that form; they are studied in fluid dynamics and magnetohydrodynamics.
The two-stream instability is a very common instability in plasma physics. It can be induced by an energetic particle stream injected in a plasma, or setting a current along the plasma so different species (ions and electrons) can have different drift velocities. The energy from the particles can lead to plasma wave excitation. [1]
While Uber stock took a hit on Thursday due to Waymo’s latest move to Miami, not all of Wall Street is convinced the Waymo threat is a death knell to Uber’s business.
Huawei Technologies asked a U.S. judge to dismiss much of a federal indictment accusing the Chinese telecommunications company of trying to steal technology secrets from U.S. rivals and misleading ...
Haha! Dog owners are all too familiar with the sniff inspection, but most inspections don't last more than a few seconds. My Husky mix tends to spend longer sniffing any bags we brought home just ...
