Rheology of Mobile Interfaces
نویسنده
چکیده
This review discusses the rheology of interfaces that separate two, immiscible fluids. Unlike interfaces at the fluid/solid boundary, these surfaces are mobile and deform. In the presence of amphiphiles that collect at these interfaces, they can become highly structured and non-Newtonian. These nonlinear responses to flow have profound implications on many physical processes and examples can be found in nature and industry. This review summarizes experimental methods in interfacial rheometry (both mechanical and optical methods are discussed), and presents their application to numerous classes of complex fluid interfaces. These interfaces come in a wide range of forms that are often directly analogous to their three-dimensional counterparts. This review presents results on classical fatty acids and alcohols, multiphase systems, rodlike amphiphiles, flexible chain amphiphiles, surface gelation, biopolymers, and two-dimensional suspensions.

متن کاملResponse of a two-dimensional liquid foam to air injection: Influence of surfactants, critical velocities and branched fracture
Experiments where air is injected into a foam confined in a Hele-Shaw cell are convenient to study the rheology of foams far from the quasistatic regime, and their limit of stability. At low overpressure, the injected air forms a ductile crack, whereas at high overpressure, it breaks the foam like a brittle material. We present new results in this configuration, complementary with previous stud...
