Abstract:

The simple vibrating systems described by the equations in the report bear little direct relation to the complex shapes and surfaces which are usually seen in zero gravity, or to those which will probably exist in the Centaur fuel tank. The simple systems do, however, have the feature in common with the complex ones that their response to a disturbance is controlled by density viscosity, and surface tension. The analytical expressions corroborate, for the simple system, the dimensional analysis which should also apply to the complex systems the one data point lies remarkably close to the proper LN2 line.
