On the feasibility of the parabolic ogival cross-section for liquid-filled toroidal vessels
Abstract eng: From a functional point of view, toroidal vessels of non-circular cross-section may offer advantages over circular toroids, but departures from the circular cross-section are fairly rare, owing to lack of adequate information on the structural performance of other shapes. Profiles with a pointed top and bottom end have operational advantages when used for storing liquids that produce scum at the top or sediments at the bottom. In this study, we use the membrane theory of shells to explore the stress distribution in liquid-filled toroidal vessels with a doubly symmetric cross-section formed by two identical parabolas intersecting along a vertical axis. Stress resultants are obtained in terms of of two non-dimensional geometric parameters of the toroid, and a parametric study is conducted on the basis of these expressions. Some insights on the structural behaviour of this type of toroidal vessel are gained, and tentative design recommendations proposed.
