Abstract

Purpose Sloshing is undesirable phenomenon and may invite instability in any type of tank partially filled with liquid. For a specially designed circular cylindrical container filled with an inviscid, incompressible, and homogenous liquid, if an annular baffle is attached to the outer cylinder wall in the annular region of the cylinder at some depth, the natural frequencies and the response of the liquid in the container undergo a drastic change. The purpose of this study is to report the sloshing modes and sloshing frequencies in the annular region of two coaxial vertical circular cylinders.

Methods An introduction of a baffle divides the liquid region into four. Boundary value problems are set up for the potential in each of these regions, and with the help of the matching conditions across the virtual interfaces, we set up a system of linear equations by solving which we determine the natural frequencies.

Results and conclusions The fundamental natural frequency of the liquid is determined for different width and positions of the baffle in addition to different configurations. It is observed that effect of baffle position on frequency is non-monotonic. It is also observed that when a baffle is placed nearer to the free surface, it has a greater significance on frequency. It is observed that frequency decreases with increasing baffle depth. The effect of the inner radius of the baffle on frequency is almost monotonic while with increasing inner radius of container, frequency increases monotonically. ANSYS is used to report the first modes of the sloshing. All our observations are supported by relevant graphs.
