The total-pressure loss in gas turbines is evaluated. 
Reynolds-averaged Navier-Stokes equations are used for numerical 
calculations. The Spalart-Allmaras model, the k -  
model, and the two-layer model and their different modifications 
allowing for the rotation of the flow and the curvature of streamlines 
are used to close these equations. The role of different corrections 
to the turbulence models for the accuracy of calculated estimates 
is elucidated.
