“…Baffle parameters (such as shape, location, spacing, etc) significantly influence the dynamic characteristics of the fluid-structure interaction problem, and a number of investigations has centred around baffle effects. Cho et al [43] employed the structural-acoustic FEM formulation to investigate the free vibration response of storage tanks with horizontal annular baffles. They carried out a comprehensive parametric study of the influence of baffle number, baffle location, baffle inner-hole diameter, liquid level, etc, on the natural frequencies and mode shapes of cylindrical tanks.…”

The aim of this study is to develop a semi-analytical method to investigate fluid-structure coupling of concentric double shells with different lengths and elastic behaviours. Co-axial shells constitute a cylindrical circular container and a baffle submerged inside the stored fluid. The container shell is made of functionally graded materials with mechanical properties changing through its thickness continuously. The baffle made of steel is fixed along its top edge and submerged inside fluid such that its lower edge freely moves. The developed approach is verified using a commercial finite element computer code. Although the model is presented for a specific case in the present work, it can be generalized to investigate coupling of shellplate structures via fluid. It is shown that the coupling between concentric shells occurs only when they vibrate in a same circumferential mode number, n. It is also revealed that the normalized vibration amplitude of the inner shell is about the same as that of the outer shell, for narrower radial gaps. Moreover, the natural frequencies of the fluid-coupled system gradually decrease and converge to the certain values as the gradient index increases.
