✦ Synopsis

A general theory is presented to account for both the in-plane and out-of-plane motions of uniformly thin toroidal shells conveying fluid. Love's general thin shell equations and a classical potential flow theory are used for the structure and fluid respectively. A general solution for the natural frequency is obtained and numerical results are presented. The effects of flow velocity on the natural frequency are discussed. It is shown that when the flow angular velocity exceeds a certain value, the shell becomes subject to buckling-type instability. The influences of various parameters upon the natural frequencies and the critical angular velocity are also clarified at the end of the paper.

This paper proposes a new matrix method for calculating critical #ow velocity of curved pipes conveying #uid, which have arbitrary centerline shape and spring supports. Its main advantage over other methods is that the corresponding characteristic equation can be reduced to a third order one, no mat
