Abstract
We consider the Navier-Stokes equations for an incompressible medium that fills at any time t ≥ 0 an open axially symmetric cylindric layer D. We find solutions of these equations in the class of motions described by velocity fields whose lines for t ≥ 0 coincide with their vortex lines and lie on axially symmetric cylindrical surfaces in D.
