Abstract
A joint testing of the specialized (VP2/3) and universal (FLUENT) packages of applied programs of the hydrodynamic and thermophysical profile is carried out on the basis of the solution of a well-known problem of recirculation flow of a viscous incompressible fluid in a lid-driven square cavity. The Reynolds-averaged Navier ? Stokes equations are solved with the aid of implicit factored computational procedures. The adequacy of chosen one-, two- four-parametric semiempirical differential models of turbulence is analysed in detail.
