Results of numerical simulation of the mixing of a turbulent 
jet with a cocurrent incompressible-fluid flow (Schmidt number Sc 
 1000 in a cylindrical channel of circular cross 
section (axisymmetric mixer) with the use of the standard k- turbulence model 
and different models for the averaged value of the mixture fraction and 
its variance have been given. For the problem of mixing of an inert 
passive impurity, two regimes of flow - the regime with the formation 
of a recirculation zone and that without its formation - have been 
considered. The formulated statistical model has been verified 
with the use of experimental data and results of calculation 
by large-eddy simulation.
