| The two-dimensional Navier-Stokes equations, which have been written down concerning generalized system of coordinates, are applied for research of unsteady flows of an incompressible liquid. The numerical decision algorithm of the initial equations is based on the method of the artificial compressibility. This method has been modified for calculation of unsteady flows, it uses schemes TVD MinMod of the second and ISNAS the third order for convective terms and central differencing the second order for viscous terms. Integration on time of the momentum equations is carried out with the help of the unilateral scheme of the second order. As a test problem, laminar flow behind a circular cylinder is being considered. |
