DYNAMICS OF ROLLER DOMAINS AT PARAMETRIC EXCITATION OF CAPILLARY WAVES IN RECTANGULAR GEOMETRY BOUNDARY

The work presents the results of experimental investigation of roller domains parametrically excited by the capillary waves. Domains rollers were oriented parallel to the different borders of the rectangular cell and perpendicular to each other. Found that depending on the initial and boundary conditions on the edges of the cell can emerge two-dimensional domains of different forms. The dynamics of the domain is determined by the movement of their fronts. A model is proposed to explain the observed phenomena, numerical calculations by which agree well with experiment.
