“…For example, Benjamin & Ursell (2) revealed unstable modes and a stability chart in 1954, using velocity potential under a linear approximation of the free surface. Dodge et al (3) and Ikeda et al (4) conducted 3-rd order nonlinear analyses by perturbation methods, showing wave forms and pressure distributions. Gerlach (5) and Hashimoto & Sudo (6), (7) investigated pressure fluctuations in the spray-excited condition.…”

Vertical sloshing is the liquid surface motion in a container forced to oscillate in the vertical direction. The present paper concerns the vertical sloshing in various equilateral-polygonal-section containers such as octagonal-, heptagonal-, hexagonal-, pentagonal-, square-and triangular-section containers together with a circular-section container, in order to generalise their sloshing modes. As a result, the authors classify the sloshing modes on the basis of the conventional circular-section-container sloshing modes.It is revealed that this modal classification has some advantages over that based on the conventional square-section-container sloshing modes. Furthermore, the stability diagrams for all the equilateral-polygonal-section containers are investigated by both experiments and computations. The present computation is based on a discrete singularity method. The proposed modal classification is useful to predict the eigen frequencies. Specifically speaking, it is found that the equivalent diameter d e1 based on the hydraulic mean depth is the most adequate as a characteristic length scale to classify all the sloshing modes. The authors show a unified formula to predict the eigen frequencies, using d e1 together with the proposed modal classification.

The dynamic behavior of a liquid storage tank placed on an elastic foundation is studied analytically and experimentally. The coupled method of FEM-BEM is firstly developed for the dynamic analysis of the fluid-structure-foundation coupled system and the accuracy of the method is demonstrated for the sloshing, ovaling and rocking oscillations. The results of the numerical analysis are compared with the results of experiments conducted with a flexible cylindrical tank placed on an elastic foundation. The effects of the flexibility of the foundation are finally investigated on the dynamic characteristics of coupled motion of the tank.
