Natural damped frequencies of an infinitely long column of immiscible viscous liquids
Abstract
Extended space flights and manned earth-orbiting space laboratories provide for manufacturing processes and experiments conditions which are not found on the surface of the earth. The availability of conditions involving highly reduced or zero gravity are of interest for many engineering disciplines, taking into account fluid mechanics, materials sciences, and crystal growth. Thus, floating zone melting under zero gravity conditions has great advantages. However, there are also certain difficulties. The floating zone has, for instance, a free liquid surface which is susceptible to dynamic disturbances. The stability problems which arise have been studied by a number of authors. The present investigation is concerned with infinitely long systems which consist of immiscible liquids of different densities and viscosities. Approaches for determining the natural damped frequencies and the decay of the motion of surface waves are discussed.
