Banded Structures in the Distribution Pattern of a Drop over the Surface of the Target Fluid

The process of establishing the line distribution of a substance when a freely falling colored droplet is immersed in a liquid at rest has been traced for the first time by the methods of high-resolution photography. The patterns of the flow of mixing liquids (drops of brilliant green and alizarin ink, which fell into the water) include vertical fibers on the surface of the crown and mesh structures at the bottom of the cavity. The linear nature of the distribution of the soluble impurity over the surface of the cavity and crown was observed in all the experiments (more than 500) in a wide range of media viscosities and sizes and velocities of the droplet at the time of contact with the host liquid. The dependence of the parameters of the emerging structure on the Weber number has been traced.
