An unsteady flow around a transversal circular cylinder 
has been analyzed on the basis of solution of Navier-Stokes and 
Reynolds equations, closed, in the latter case, using one- and two-parameter 
differential models of turbulence, by the implicit factorized method 
with the use of different-density structured and nonstructured grids. 
Solvers of specialized multiblock and universal packages have been 
tested.
