Vortex - Wikipedia
网页In the dynamics of fluid, a vortex is fluid that revolves around the axis line. This fluid might be curved or straight. Vortices form from stirred fluids: they might be observed in smoke rings, whirlpools, in the wake of a boat or the winds around a tornado or dust devil. Vortices are an important part of turbulent flow.
Vortex, Physics: WSM explains Vortex Theory
网页Definition of Vortex Theory. Vortex theory, advanced by Thomson (Lord Kelvin) on the basis of investigation by Helmholtz, that the atoms are vortically moving ring-shaped masses (or masses of other forms having a similar internal motion) of a homogeneous, incompressible, frictionless fluid.
Vortex: Fluids & Mechanics Science Activity - Exploratorium
网页The essence of a vortex is that objects are drawn together toward the center, then miss! Spiral waves form in the water surface of the vortex. These waves appear to move in slow motion as they travel upward through the downward-flowing water.
Science Behind the Vortex - StudiousGuy
网页A vortex is a portion of fluid rotating about an axis line. Vortexes or vortices exist in nature in a number of forms such as tornadoes, hurricanes, whirlpools, etc. A vortex can also be observed in real life easily by spinning a water bottle, draining the sink, swirling the cup of tea, etc.
Vortex | physics | Britannica
网页…chain of particles, called a vortex. As a result of the original motion, some particles were gradually ground into a spherical form, and the resulting intermediary space became filled with the surplus splinters or “grindings.” Ultimately, three main types of particles were formed: (1) the splinter materials, which form the… Read More
Vortex - New World Encyclopedia
网页A vortex (plural vortices) is a rapidly spinning, circular or spiral flow of fluid around a central axis. The swirling motion tends to suck everything within the fluid toward its center. The speed and rate of rotation of the fluid are greatest at the center, and decrease progressively with distance from the center.
Introduction - UMD
网页A vortex is a type of solitary wave. James Scott Russell was one of the early researchers into solitary waves. His report on solitary waves described the moment that inspired him to spend the next ten years of his life studying solitary waves:
Fluid Mechanics: A Very Short Introduction - Oxford Academic
网页‘Vortices’ is devoted to a common example of fluid motion, namely the localized swirling motion of a fluid called a vortex, starting by highlighting some examples of vortices in our daily life, most famously those in the weather system (cyclones and tornadoes).
Vortex Theories in the Early Modern Period | SpringerLink
网页2020年1月23日 · Introduction. In the early modern period, various philosophers and scholars have proposed the idea of the vortex, i.e., of a fluid in rotational movement around an axis, in particular Descartes, to explain the movement of the planets around the Sun, in the same direction and in approximately the same plane.
Vortices in physics - ScienceDirect
网页2002年3月15日 · In the context of vortex physics a vortex or “vortex line” is a physical object in the sense that it satisfies conservation laws, can be generated and destroyed, and can move. A vortex in a frictionless fluid cannot end inside the fluid: it either forms a closed loop or it starts and ends at the surface or at the container wall [2] .
