Forced Oscillations of Isothermal Liquid Bridges

Abstract

The forced oscillations of a liquid column held by surface tension forces between two solid supports in a zero gravity environment are analysed by using a linear threedimensional model in which viscosity effects are not considered. Forced oscillations are imposed to the liquid column by vibrating the supporting disks (with particular attention to the in phase or in counter-phase cases), and the response of the liquid bridge (interface deformation and pressure and velocity fields) is obtained. The results arc compared with those obtained with one-dimensional models
