Abstract (English):
The stages of mixing liquid in a turbulent flow, whereby for calculating the dependence of the mixing time at the micro level that takes into account the size of the maximal effect of turbulent fluctuations, particularly at low intensity mixing. The sizes of the areas with the maximum ripple in which the mixing takes place at the micro level.
