RESONANCE INTERACTION OF BOILING DROPS AND OF TURBULENT FLOW IN UNSTABLE EMULSION
Alexander Rozentsvaig
|
Abstract: Phase transformations in the volume of dispersed droplets significantly affect the course of kinetic processes in unstable liquid emulsions. The movement of the interface due to vaporization creates disturbances in the flow of the continuous medium of the emulsion. Low-boiling droplets change the nature of their interaction with the turbulent flow of a continuous medium when their size changes. Superheated droplets change the nature of their interaction with the turbulent flow of a continuous medium when they change their size. Stochastic nucleation and growth of viable vapor bubbles associated with hydrodynamic generation of internal pressure pulsations are considered. The breakage mode of superheated droplets as a result of resonant interaction with external pulsations of the turbulent flow velocity is justified on the basis of qualitative analysis. |
Keywords and phrases: liquid emulsion, turbulence, dispersed drop, phase change, mode of boiling, mode of breakage, resonance phenomena.
