Propagation of small perturbations in an ideal turbulent medium
Abstract
The paper presents a theoretical study of the propagation of small perturbations of the velocity field and the tensor of singlepoint correlations in an ideal turbulent medium. The motion of this medium is described by a 'truncated' system of Reynolds equations obtained by neglecting 'viscous' components and the 'unclosed' part of the initial equations. In the simplest case of the translational motion of a uniformly turbulent isotropic ideal medium, the propagation of the small perturbations, considered in a mobile coordinate system, is governed by an electromagnetic field generated by stably distributed sources. The divergence of the correlation tensor and the vorticity of the smallperturbation field are taken as the 'electric' and 'magnetic' components of this electromagnetic field. The 'charge' density corresponds to the density of the initial distribution of turbulence sources.
