To research the flow around rotating circular cylinder is applied the
unsteady incompressible Navier-Stokes equations. The numerical algorithm is
based on a method of artificial compressibility, the implicit three-layer
scheme of the second order with subiterations during integration on time,
difference scheme the third order with flux vectors splitting for convective
terms and central-difference scheme at integration of viscous terms. The
velocity profiles, vorticity fields, distribution of pressure and friction
coefficients over cylinder surfaces, drag and lift force coefficients are
analyzed for a laminar regime of the flow.
