Abstract: The unsteady fluid-dynamics of rigid or flexible cylinders in narrow annular flows and the related flow-induced vibrations and instab ilities are discussed. The paper presents a synthesis of the authors' recent studies formulating a more rigorous ana lysis for both potential and viscous annular flows. The case of noncylindrical annular geometries is also treated.
