Response of a Liquid Column to Counterdirectional Excitation
Abstract
A finite cylindrical liquid column consisting of incompressible and frictionless liquid subjected to a counter-directional axial harmonic excitation is modeled. The liquid system is assumed to be in a zero-gravity environment and held together by surface tension, which acts as the restoring force. The response of the system has been determined for a free surface elevation and velocity distribution. In addition, transient behavior was treated and damping introduced in the resonance terms. It was found that the first resonance response is sharply tuned and could easily be missed by a sweeping experiment. The investigation was performed for the design of the German D-2 Spacelab-mission 'LICORE'.
