Dynamics of interfacial and surface waves in a layered fluid

摘要

In this paper the dynamics of a layered fluid system, constituted by two superimposed immiscible liquid layers inside a moving container, is considered. Such layered fluid system presents two moving boundaries: the separation surface and the free surface. The motion imposed to the container - an oscillating rotation with given amplitude and frequency - generates waves on the moving surfaces, whose dynamics is analysed by means of a suitable visualisation device. Several wave configurations are obtained by varying the angular frequency of the exciting motion and some of them compared with those obtained by numerical simulations.
