TL;DR: In this paper, a semi-analytical finite element method was proposed for elastic conical shells conveying fluids, where the structural equations were based on the shell element proposed by Ramasamy and Ganesan, and the fluid model was based on velocity potential formulation used by Jayaraj et al.

Abstract: This paper describes the method of determining the normal modes of vibrations and natural frequencies of elastic shells of revolution with an arbitrary meridian, partially filled with a fluid. The modes of vibration of the shells with fluids are determined as a linear combination of the natural modes of vibration in vacuum. The solution of the problem of hydroelastic vibrations has been obtained using the methods of the boundary element (BEM) and the finite element (FEM). Numerical investigations of vibrations of hemi-spherical shells conveying fluid have been conducted and analyzed. Illustrative examples are provided to demonstrate the accuracy and efficiency of the developed numerical procedure.

TL;DR: In this article, the authors proposed added mass and added damping to address the effects of vibration of the damping material on the vibration of a pipe, which can be used to predict the vibration reduction effect in detail, but such analysis requires considerable computation time.

TL;DR: In this article, a coupled formulation based on the semi-analytical finite element technique is developed for composite shells conveying fluid, where the structural finite element formulation is from Ramasamy and Ganesan (1998 Computers and Structures70, 363-376), while the fluid part is modelled by the characteristic wave equation.
