Effects of internal flow and viscosity ratio on measurements of dynamic forces between deformable drops.
A model that has been shown to give very accurate predictions of dynamic forces between deformable emulsion drops and bubbles is used to quantify the effects of internal flow and viscosity ratio on the hydrodynamic interaction in such systems. The results demonstrate that direct force measurement using an atomic force microscope can readily differentiate whether the interfaces of drops of different viscosities respond as immobile (no-slip) or fully mobile (no tangential shear stress) boundaries.
