Abstract

High-speed video recording methods are used to track the distribution patterns of compound droplets (consisting of two immiscible liquids: a core and a shell) over the deformed surface of a receiving liquid in the impact mode, where the droplet’s kinetic energy at the moment of contact with the receiving liquid is significantly greater than the surface potential. The droplet core is an aqueous solution of alizarin ink and the film substance is sunflower oil. This contrasts with the impact of homogeneous droplets in a sectoral structure of the distribution of the substance with thin horizontal periodic elements.
