3D transport can be affected by hydrodynamic instabilities of geophysical vortices; however, how the instabilities affecting 3D transport is not clear. Focusing on barotropic, inertial and 3D instabilities, we investigate the joint impacts of instabilities on 3D transport by using analytical methods and...
When these vortices are tilted from horizontal to vertical, you get fire whirls. Fire whirls have been known to hurl flaming logs and burning debris over considerable distances. "There's another way that you can tilt the vorticity. That is it can be titled without breaking into fire whirls...
“If a flyer is displaced from its position, the vortices or swirls of flow left by the leading neighbor help to push the follower back into place and hold it there,” explains Ristroph, director of NYU’s Applied Mathematics Laboratory, where the experiments were conducted. “This means the...
How do Rayleigh waves form vortices? What type of mechanical wave is a water wave? What do vertical and horizontal surface waves have in common? What type of wave makes up sound? Do surface waves have a high amplitude? How do electromagnetic waves work? How does a radio wave differ from...
The polar vortex, also called the circumpolar vortex, is a spinning air mass around a pole caused by the Coriolis effect. There are two polar vortices...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
Small dust devils sometimes form when winds flow over hot deserts, and wildfires can also produce climbing vortices of flame and ash called fire whirls. Scientists have even observed dust devils on Mars and spotted solar tornadoes whipping out from the sun. In a tornado, the same sort of ...
If the angle of attack is too large or the surface of the wing is not smooth (too sharp of a curve for a given speed), then the air flow from in front of the wing tends to separate away from the surface then form large vortices (or one very large vortice) above a wing ...
Topology tells us that topological vortices and antivortices can form new spacetime structures via the synchronous effect of superposition, deflection, or twisting of them. Mathematics does not tell us that there must be God particles, ghost particles, fermions, or bosons present. When physics and ...
Saturation by zonal flowVia the Reynolds work (Sect.5.4.4), energy from the turbulence is transferred into the zonal flow and thus saturates the growth of the instability. This can happen when vortices are tilted by an existing background flow; if this is not the case, the zonal flow devel...
The theory is that the shape and design of these NACA ducts encourages vortices to form, reducing static pressure and enhancing the efficiency of the flow through the inlet. As air flows towards the narrow end of the duct, it flows down the gentle slope and into the inlet. But the air ...
