| Rotational bulk rheometers may be used as interfacial shear rheometers (ISR) by supplementing them with proper accessories that allow one to impose a shear on a fluid-fluid interface in a controlled manner. Actually, most rotational rheometer manufacturers sell fixtures for interfacial shear rheometry measurements, such as the bicone, the Du Nouy ring, or the double-wall ring (DWR) fixtures. However, recovering the proper values of the dynamic moduli from the torque and angular displacement data is far from trivial due to the coupling between the subphase and the interfacial flow fields. Moreover, a low viscosity fluid is usually chosen for the subphase, and the low interfacial pressure regimes usually have low interfacial viscosity. Therefore, fluid inertia very often comes into play, which results in nonuniform shearing profiles both at the interface and the subphase, further complicating then the data analysis. | |
