Abstract
Considering initial axial loads dynamics and stability of an inner functionally graded cylindrical shell conveying swirling fluid ie water in the annulus between the flexible inner shell and the identical rigid outer shell are investigated by the traveling wave approach Shell motions are described by Donnell’s thin shell equations The fluid forces associated with shell motions are treated in the frame of the potential flow theory The theoretical analysis is conducted by the zerolevel contour method The critical velocities of losing stability are determined The influences of angular flow on the critical axial velocity and axial flow on the critical annular velocity are studied Moreover effects of the magnitude and the direction of initial axial loads on the critical velocities are fully discussed
