摘要：
An exact analytical solution is given of the Navier-Stokes equations for stationary axisymmetric flows of a viscous incompressible liquid. The equations describe a single vortex formation with potential twisting of an initial flow. It is shown that the kinematic characteristics of the flow does not depend on the Reynolds number whereas the pressure depends on its. The vortex formation, obtained in numerical calculations, corresponds the structure, observed in experiments.
