Abstract
Abstract
Numerical simulation is presented, which models the evolution of the initial perturbation in axisymmetric subsonic flow of an ideal gas. The undisturbed flow is an axial flow perturbed by an azimuthal velocity, or a twist of the flow around the axis of symmetry. The twist leads to the establishment in the flow of an annular or ball vortex with increasing or decreasing radial axial velocity of the undisturbed flow, respectively.
