COAGULATION OF DROPS OF DIFFERENT VISCOSITY IN A TURBULENT-FLOW OF A VISCOUS-LIQUID

The coagulation of nonderformable drops of different viscosity in a turbulent liquid flow of another viscosity was studied on the basis of the turbulent diffusion model. The hydrodynamic force of resistance, the forces of molecular attraction and electrostatic repulsion that accompany the relative motion of the drops in the field of turbulent pulsations were taken into account. The frequency of drop coagulation and the emulsion stability factor were determined. The most attention was paid to the dependence of these parameters on the viscosities of the interacting drops. The difference of the drop viscosities was shown to have a significant effect on their coagulation rate.
