Self-excitation of the low-frequency vibration of a liquid in the case of the high-frequency vibration of the container
Abstract
Experimental data are presented on the behavior of a liquid in the case of the high-frequency (50-70 Hz) vibration of the container resulting in the spouting of liquid drops from the free liquid surface and excitation of liquid oscillations with a frequency that is a factor of 5-20 less than that of the vibration-producing force. The dependence of these phenomena on the frequency and amplitude of the longitudinal exciting force, transverse container vibrations, and some container parameters is determined. The effect of the liquid behavior on the vibrations of the tank and the adjacent elastic structures is examined.
