In systematic and comprehensive research, dynamics of a confined liquid bridge between parallel solid plates are studied. Different responses from the liquid bridge including rupturing, detaching, or time periodic motion are predicted by increasing the frequency. Regardless of the plates wettability property, there is a critical frequency as the liquid bridge response determinant. Increasing the frequency of external flow has a stabilizing effect on the liquid bridge motion by reducing the throat and footprint fluctuations. Liquid bridge response and external flow do not behave in the same phase.
