Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …
