Bottom and Surface Proximity Effects on the Added Mass of Rankine Ovoids.
Abstract
The free-surface and bottom-proximity effects on the added mass of Rankine ovoids of various length-to-diameter ratios were experimentally investigated by vertically oscillating the ovoids normal to their major axis. The results have shown that the bottom-proximity increases the added mass and the free-surface proximity decreases it. Furthermore, the added mass increases with increasing length-to-diameter ratio, i.e., for more cylinder-like ovoids, and approaches that predicted analytically for an infinitely long cylinder.
