N2 - The paper investigates the possibility of equilibrium solid-body rotation of a vortex bundle diverging at some height from a cylinder axis and terminating on a lateral wall of a container. Such a bundle arises when vorticity expands up from a container bottom, eventually filling the whole container. The analysis starts from a single vortex, then goes to a vortex sheet, and finally, addresses a multilayered crystal vortex bundle. The equilibrium solid-body rotation of the vortex bundle requires that the thermodynamic potentials in the vortex-filled and in the vortex-free parts of the container are equal, providing the absence of a force on the vortex front separating the two parts. The paper considers also a weakly nonequilibrium state when the bundle and the container rotate with different angular velocities and the vortex front propagates with the velocity determined by friction between vortices and the container or the normal liquid moving together with the container.
