This paper presents the results of  testing of the  
v2-f model of turbulence with the examples 
of two-dimensional flow of an incompressible fluid and heat exchange 
with the walls of an abruptly expanding duct. The calculation data 

have been compared to the known experimental data, and the data of 
direct numerical simulation, as well as to results of calculations 
with the use of two versions of the k- model.
