Abstract: The possibility of applying the Kac equation to the simulation of small-scale turbulence is explored. The hypothesis is substantiated that the formation of a flow regime similar to the actual turbulent one can be qualitatively described as based on the analysis of the properties of the Kac equation.

Key words: mathematical simulation, small-scale turbulence, probability-theoretic Kac equation, solution of fluid dynamic equations, Boltzmann equation.
