Important two-phase fluid mechanics problems that are dominated or significantly affected by capillary effects are not oddities but rather daily events in our lives. Seemingly unrelated topics such as the economics of satellite television and pulmonary health and safety research share capillary fluids physics. Current and future miniaturized two-phase heat transfer loops and fuel cells possess similar concerns. This seminar presents research in a number of capillary fluids topics on Earth and in orbit. An energy method code, Surface Evolver, is ....etc

Electrorheological fluids are suspensions of extremely fine non-conducting particles (up to 50 micrometres diameter) in an electrically insulating fluid. The apparent viscosity of these fluids changes reversibly by an order of up to 100,000 in response to an electric field. For example, a typical ER fluid can go from the consistency of a liquid to that of a gel, and back, with response times on the order of milliseconds. The effect is sometimes called the Winslow effect

The ER effect

The change in apparent viscosity is dependent on the ap ....etc

The uniaxial extensional viscosity is a fundamental material property of a fluid which characterizes the resistance of a material to stretching deformations. For microstructured fluids, this extensional viscosity is a function of both the rate of deformation and the total strain accumulated. Some of the most common manifestations of extensional viscosity effects in complex fluids are the dramatic changes they have on the lifetime of a fluid thread undergoing capillary breakup. In a pinching thread, viscous, inertial and elastic forces can all r ....etc
