Comparative analysis of the calculation data on an unsteady flow around a circular cylinder obtained using the VP2/3 and fluent packages and the Spalart-Allmaras and Menter turbulence models

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.
