In fluid dynamics, a vortex (PL: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterise vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis. In the absence of external forces, viscous friction within the fluid tends to organise the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries some angular and linear momentum, energy, and mass, with it. (Wikipedia).

What Is Turbulence? Turbulent Fluid Dynamics are Everywhere
Turbulent fluid dynamics are literally all around us. This video describes the fundamental characteristics of turbulence with several examples from nature and from engineering. We discuss how turbulent fluids are unsteady, three-dimensional, mixing, and multiscale. We also describe how

How to Make a High Power Vortex Cannon
This project was inspired by many things. Large commercially made vortex cannons are used (theoretically) to disrupt hail formation and prevent damage to farmland. German scientists during WWII also constructed a large vortex cannon designed as an anti air gun. The plan was to use a powder

Carlo Barenghi: Classical and non-classical flows of superfluids
Abstract: Superfluids are remarkable because they lack mechanisms of viscous dissipations, and because vorticity is concentrated in thin vortex lines - a property which arises from the existence and uniqueness of a macroscopic wave function. In this talk I shall review recent experiments a
