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. 1 Introduction The present work consists in an experimental and theoretical study on the sloshing
