A modified two-parameter model of turbulence for calculation 
of flows with a considerable flow curvature is considered. Account 
for the effects of anisotropy is based on correction of empirical 
coefficients, which enter into the equation of transfer of dissipation 
of turbulent kinetic energy, using the Richardson number. It is suggested 
to apply a correction not to the entire region of calculation, but 
to the portions where the Richardson number takes on certain values. 
Satisfactory agreement of calculation results with experimental data 
of different authors and a slight increase in computational costs 
allow one to draw the conclusion on the possibility of employing the 
suggested approaches in engineering practice.
