The authors formulate and study an elementary one-dimensional model mimicking some of the features of fluid turbulence. The underlying vorticity field corresponds to a parallel flow. Structure on all scales down to the numerical resolution is generated by the action of baker`s maps acting on the vorticity of the flow. These transformations conserve kinetic energy locally in the Euler model, while viscous diffusion of vorticity occurs in the Navier-Stokes case. The authors apply the model to the study of homogeneous fully, developed turbulence, and to turbulent channel flow.
