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, the course of the process, calculate its optimal physicochemical parameters for precise, rather than experimental use, in order to obtain aerosols, mixtures with absolutely immiscible components.
The article reveals the mechanism of intensive mixing of liquid in a hermetic vessel with above-fluid air shell in the process of vibroturbulization, which leads to a strong dispersion of air bubbles, formed from the above-fluid air shell, uniform saturation of the fluid with them and the formation of a uniformly saturated gas-liquid mixture.
The author shows the application of this intensive mixing in technological processes, using the example of advanced foam materials production.
The obtained results permit to use this intensive mixing to obtain any homogeneous multiphase mixture in each specific case.
