What is vortex in simple words?
1 : something that resembles a whirlpool the hellish vortex of battle — Time. 2a : a mass of fluid (such as a liquid) with a whirling or circular motion that tends to form a cavity or vacuum in the center of the circle and to draw toward this cavity or vacuum bodies subject to its action especially : whirlpool, eddy.
What is a vortex ks2?
A vortex can be defined as a spinning flow of fluid or gas. These strong but invisible rings can persist and travel over surprisingly long distances. These rings are generally referred to as toroidal vortices.
What is a vortex in science?
In fluid dynamics, a vortex (plural vortices/vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved.
What is a vortex of water?
The best example of what is ordinarily thought of as a vortex is the whirlpool that is formed where the water runs out of a bath or basin. There is a widespread belief that this always spins one way, clockwise or counter-clockwise, and that this is due to the rotation of the earth.
What causes vortex in water?
When the water level and pressure drop low enough, the water surface can hold back the water and stop the flow completely. If you spin the bottles around a few times, the water in the upper bottle starts rotating. As the water drains into the lower bottle, a vortex forms.
How does a vortex work for kids?
Vortexes work with gravity. As the water is swirled around, it is drawn to the center by gravity. The glitter is held in place by centrifugal force until the vortex slows and the glitter falls back to the bottom of the beaker.
What is a vortex in sport?
The vortex howler event is a personal challenge, in an attempt to throw the howler as far as possible! Number of participants: Individual. Purpose of activity: Increase pupil physical activity through a fun individual or team competition.
What is a vortex and how does it work?
Air that rotates around an axis (like a tornado) is called a vortex. A vortex tube creates cold air and hot air by forcing compressed air through a generation chamber, which spins the air at a high rate of speed (1,000,000 rpm) into a vortex.
What is a vortex in a pool?
Vortex pool: An oval-shaped track filled with 3 feet, 6 inches of water that creates a current with jets—ideal for walking.
What is the motion of the swirling water in the bottle?
When you swirl the water, it rotates as it falls down. The water spiraling down from the top bottle into the bottom one moves faster and faster as it falls. The faster a fluid moves, the lower its internal pressure (this is called Bernoulli’s Principle, named after the scientist who discovered it).
How do you play Vortex sport?
Students stand in a circle (make it as big as possible) and pass the vortex around the circle while one person runs around the outside to try and ‘beat the bomb’. Class can be divided into two teams and score a point for each student who beats it. Teams of even numbers set out a series of distances eg.
What is a Nerf Vortex?
Vortex is a series of Nerf disc blasters that was released on September 10, 2011.
What is human vortex?
Welcome to the Human Vortex Training Channel! This channel is dedicated to strength training for cyclists and triathletes looking to get expert insights, tips, and tricks for better strength, power, mobility, improved activation, and resiliency.
Why do vortex rings form?
Releasing air underwater forms bubble rings, which are vortex rings of water with bubbles (or even a single donut-shaped bubble) trapped along its axis line. Such rings are often produced by scuba divers and dolphins.

What is a polar vortex and what causes one?
During winter, the polar vortex at the North Pole expands, sending cold air southward. This happens fairly regularly and is often associated with outbreaks of cold temperatures in the United States. If you’ve heard of a polar vortex, you might know it has something to do with very cold weather. But what exactly is a polar vortex?
How are vortexes formed on a boundary?
Another form of vortex formation on a boundary is when fluid flows perpendicularly into a wall and creates a splash effect. The velocity streamlines are immediately deflected and decelerated so that the boundary layer separates and forms a toroidal vortex ring.
What is an irrotational vortex?
Irrotational vortices are also called free vortices . For an irrotational vortex, the circulation is zero along any closed contour that does not enclose the vortex axis; and has a fixed value, Γ, for any contour that does enclose the axis once. The tangential component of the particle velocity is then .
