It was animated by Canadian studio Bardel … In chaos theory and fluid dynamics, chaotic mixing is a process by which flow tracers develop into complex fractals under the action of a fluid flow. The flow is characterized by an exponential growth of fluid filaments. Even very simple flows, such as the blinking vortex, or finitely resolved wind fields can generate … See more Fluid flows Two basic mechanisms are responsible for fluid mixing: diffusion and advection. In liquids, molecular diffusion alone is hardly efficient for mixing. Advection, that is the transport of matter … See more The birth of the theory of chaotic advection is usually traced back to a 1984 paper by Hassan Aref. In this work, Aref studied the mixing induced by two vortices switched alternately on and off inside an inviscid fluid. This seminal work had been made possible by earlier … See more Lyapunov exponents If the flow is chaotic, then small initial errors, $${\displaystyle \delta {\vec {x}}}$$, in a trajectory will diverge exponentially.
