Dynamic stabilization of Rayleigh capillary instability (Q1315639)

The effect of high-frequency vibrations on the stability of a cylindrical liquid interface is studied. It is shown that vibrations circularly polarized in the plane of the normal section can suppress the development of instability however great the length of the liquid cylinder. The effect of the density ratio of the liquids and the dimensions of the rigid outer shell on the stability of the system is investigated. It is shown that vibrations can stabilize the cylindrical interface only if the radius of the shell is not too great as compared with the radius of the liquid cylinder.
