The ArnoldāBeltramiāChildress (ABC) flow or GromekaāArnoldāBeltramiāChildress (GABC) flow is a three-dimensional incompressible velocity field which is an exact solution of Euler's equation. Its representation in Cartesian coordinates is the following: [1] [2]
where is the material derivative of the Lagrangian motion of a fluid parcel located at
It is notable as a simple example of a fluid flow that can have chaotic trajectories.
It is named after Vladimir Arnold, Eugenio Beltrami, and Stephen Childress. Ippolit S. Gromeka's (1881) [3] name has been historically neglected, though much of the discussion has been done by him first. [4]
