Section snippets Drop breakage and coalescence in colloid mills. When an emulsion is passed through the narrow gap between the stator and the rotor rotating at high angular velocity (Fig. 1(a)), drop tends to stretch due to the very high shear rate γ ̇ (10 4 –10 6 1/s). When the ratio of the viscous stress acting on the drop to the interfacial tension …Web
