Vibration cylindrical shells containing flowing fluid
 Zolotarev, Igor
The natural frequencies of free vibration of a circular cylindrical shell containing flowing inviscid fluid are studied. The numerical results obtained by use simple 1-D shell theory are compared with results obtained by use 3-D shell theory and by us NSYS numerical package. Critical flow velocity is analyzed for several shape mode of studied cylindrical shell.

On the solution of a natural vibration of cylindrical shells in interaction with flowing fluid
 Zolotarev, Igor ; Pelletier, D.
The present paper is a contribution to the solution of a natural vibration of circular cylindrical shells in interaction with flowing inviscid fluid. The mathematical model of the studied system contains general boundary conditions of the shell for ends clamped elastically and allows to use the method of solution are based on the [1,2,4,5]. A new more accurately algorithm for calculation of the action of flowing fluid on the vibrating surface of the shell and frequency-modal properties of the studied system there are presented. Obtained results correspond to the earlier calculations of the natural frequencies and its variations on the flow velocities [4,5].
