An enlargement of the region of nonlinear stability is shown as the radii ratio is increased. On the other hand, the flow always turns out to be linearly stable.

Abstract
A numerical investigation of the eigenvalue problems related to both the energy and the linear theory of stability of a Newtonian liquid between sliding pipes is presented. An enlargement of the region of nonlinear stability is shown as the radii ratio is increased. On the other hand, the flow always turns out to be linearly stable.
