Crisis phenomena arising in a subsonic air flow around 
a thick airfoil with vortex cells have been numerically simulated 
in the process of solving the nonstationary equations of mass and 
energy conservation and Reynolds equations closed by a model of 
shear-stress transfer with the use of the finite-volume factori-
zation method.
