Abstract
The virtual mass of a sphere oscillating within a fixed concentric spherical shell filled with water was determined experimentally for seven sphere-to-shell diameter ratios between 0 and 0.865. Laboratory measurements of the virtual mass for diameter ratios less than 0.520 agreed closely with the theoretically predicted values based on a potential flow analysis. For ratios greater than 0.520 the virtual mass increased more rapidly than the potential flow theory indicated with an increase of 33% for a diameter ratio of 0.865.
