Rotational motion of fluid around a central axis. A type of vortex specifically in water bodies. 15 Occurrence Can occur in any fluid, including air and water. Occurs only in water. 14 Formation Causes Varied, including fluid density and temperature differences. Often caused by water currents me...
Figure 1: Vortex Meter Calculation of Flow Velocity The vortex-shedding phenomenon can be observed as wind is shed from a flagpole (which acts as a bluff body); this is what causes the regular rippling one sees in a flag. Vortices are also shed from bridge piers, pilings, offshore dril...
What causes the most erosion on Earth? What orogeny formed Pangea? What caused the ice age 10,000 years ago? What is the main cause of uplift during continental collision? What caused Earth to develop layers as it cooled? What causes a polar vortex to move south?
Explore what causes jet streams and see how the Coriolis force plays a role in current jet streams. Related to this Question What is a circumpolar vortex? What is a vortex? What are Polar Easterlies? What is a vortex in a tornado? What is the polar jet stream? What does a polar ...
The downward flow of the water into the drain begins to rotate, and as the rotation speeds up, a vortex forms. Why does the water start rotating? There are many explanations, but here's one way to think about it: Imagine yourself as a particle in the water, suddenly pulled toward the...
What causes a Camel Toe In most cases, extremely tight-fitting clothing plays a significant role and is one of the common causes. Fabrics such as 100% spandex, linen, polyester, and rayon may enhance the appearance of the mons pubis and labia, especially in warmer weather. Bottoms with a ...
The drag crisis is associated with a transition from laminar to turbulent boundary layer flow adjacent to the object. For cylindrical structures, this transition is associated with a transition from well-organized vortex shedding to randomized shedding behavior for super-critical Reynolds numbers, eventua...
polar vortexA distinctive feature of the Martian atmosphere is that the winter polar vortices exhibit annuli of high potential vorticity (PV) with a local minimum near the pole. These annuli are seen in observations, reanalyses, and free-running general circulation model simulations of Mars, but ...
What causes vortex stretching? In fluid dynamics, vortex stretching is the lengthening of vortices in three-dimensional fluid flow, associated with a corresponding increase of the component of vorticity in the stretching direction—dueto the conservation of angular momentum. ... In the end, this res...
