Abstract

The influence of direct atomic–molecular mechanisms (considering the structure of the Gibbs potential distribution) and hydrodynamic mechanisms (with flows and waves) of energy transfer is analyzed, and their effect on the structure and dynamics of the impact flows of a freely falling drop is evaluated. The analysis of the processes is carried out taking into account the properties of complete solutions of the system of fundamental equations describing waves, ligaments, vortices, and flows. The results of visualization of mass transfer and the evolution of thin fibrous structures during the formation and collapse of the primary cavity and the subsequent rearrangement of flow patterns in neutral and chemically reacting media are presented. Possible applications are discussed.
