Abstract
The linear theory of propagation of a spherical wave layer is used to treat the principles of simulating turbulent process and the criteria of its similarity. The mechanism of turbulence is given for a flat channel defined by two walls and for a square tube. We use this channel as an example to demonstrate the effect of the wave layer properties on velocity pulsations, as well as the effect of the characteristics of a sequence of disturbances on the structure of pulsations. The model is used to describe the structure of a plasma channel developed by a Bessel beam of laser radiation. The Mathematica-4 language is used for simulation.
