Microfluidics to Study Transport Phenomena
Presented by Steve Hudson
Polymers Division, Complex Fluids Group
In microfluidics the fluid composition, flow kinematics and timing of events are well controlled. This technology therefore is useful for new measurement methods and corresponding advances in understanding fluid dynamics and rheology. I will describe our work on emulsions, interfacial tension, mass transfer kinetics, interfacial adsorption, and interfacial rheology. In these examples, the small scale of droplet size (similar to human hair) is relevant not only for applications but it also gives unique or superior measurements.
