Abstract

High-speed video recording methods are used to track the mass distribution patterns of composite droplets (consisting of two immiscible liquids: a core and a shell) by the deformed surface of a receiving liquid in the impact and intrusive modes. Flow modes are determined by the ratio of the kinetic and surface potential energies of the droplet at the moment of contact (free-fall height and droplet diameter). The droplet core consists of an aqueous solution of alizarin ink and the film material is sunflower oil. In the intrusion mode, the shell is maintained for a short period of time and the droplet sinks as a solid with minor deformations. In the intrusive mode, the impact of homogeneous droplets differs from the sectoral structure of the material distribution with thin horizontal periodic elements.
