Vibration cylindrical shells containing flowing fluid
Zolotarev, Igor
The natural frequencies of the free vibration of a circular cylindrical shell containing flowing inviscid fluid are studied. The numerical results obtained by use ANSYS numerical package are analyzed for frequency-modal properties of two different numerical models and compared with results of the analytical calculations. Application different FEM models that are created with using fluid-structure-interaction elements (FSI) and without it are analyzed too.

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.
