Vortex ring. Spark photography image of a vortex ring in flight. A vortex ring, also called a toroidal vortex, is a torus-shaped vortex in a fluid or gas; that is, a region where the fluid mostly spins around an imaginary axis line that forms a closed loop. The dominant flow in a vortex ring is said to be toroidal, more precisely poloidal.
Lorenz Attractor in 3D Details Category: Chaos Theory Published: Monday, 10 January 2011 02:32 Lorenz attractor is a fractal structure corresponding to the long-term behavior of the Lorenz oscillator. The Lorenz oscillator is a 3-dimensional dynamical system that exhibits chaotic flow, noted for its lemniscate shape. So this ting came out of the mind of the man who coined the term butterfly effect and one of the firs men who took chaos theory seriously. So lats look at the shape in 3D (WebGL).
