Observations of the Free-Falling Drop Impact Flows

Experiments have identified two modes of coalescence of a free-falling drop of liquid mixing with a deep target fluid at rest–a slow intrusive mode and a fast impact mode. The influence of the energy transfer and transformation processes on the flow dynamics and structure is analyzed. Experimental planning and data interpretation were carried out subject to the properties of complete solutions to the system of fundamental equations of inhomogeneous fluid mechanics. The transfer of the results to flows in facilities and in the environment is discussed.
