Coalescence and fragmentation of drops in an isotropic turbulent flow

Coalescence and fragmentation of drops in an isotropic turbulent flow are considered. Equations for the minimum stable and maximum unstable sizes of drops were suggested. The coalescence frequency in liquid-gas and liquid-liquid systems was determined by analytically solving mass exchange equations....

Description
Summary:Coalescence and fragmentation of drops in an isotropic turbulent flow are considered. Equations for the minimum stable and maximum unstable sizes of drops were suggested. The coalescence frequency in liquid-gas and liquid-liquid systems was determined by analytically solving mass exchange equations. The drop fragmentation frequency in an isotropic turbulent flow was determined. The evolution of the size and time distribution function of drops was studied using the Fokker-Planck equation. A comparison with experimental data gave satisfactory agreement.
