Plasma turbulence and percolation effects

Summary form only given. Essential deviation of transport processes in turbulent fluids and plasma from classical bechaviour leads to a necessity of search of new approaches and scaling laws. This paper deals with the relationship between the scalings based upon fractal and upon percolation concepts of turbulence. Renormalization methods of quasilinear equations in anisotropic mediums are considered. The anisotropy of medium is thought to he due to the presence of a strong magnetic field. It is shown that the Corrsin conjecture about diffusive nature ofdecorelations appears to be the basis for such renormalization. The problem of relation between the Lagrangian corelation function and the Euler one is considered in anisotropic medium. Effectiveness of Corrsin??s randomization to describe the transport of panicles for the model with zonal flow is demonstrated. The common character of correlation approximation for the models ofcorrsin??s, Taylor-McNamara??s is discussed. The Dreizin-Dykhne model [I], the Kadomtsev-Pogutse method [2], and double diffusion [3] are investigated io detail. The analysis is made of ??rehuns?? effects role and memory effects. The relation between the description methods oftransport in systems with convective cells and percolation method is considered. The description methods of the strong longitudinal correlation effects are observations
