Dynamic boundaries in complex fluids
In a simple fluid the boundary between the fluid and any solid surface is normally a static quantity defined by boundary conditions given at the beginning of the problem. Complex fluids, however, allow greater control of interfacial phenomena via the extra degrees of freedom associated with their internal structure and composition. I will illustrate how this allows the boundary conditions to be manipulated both spatially and temporally. This effect can then be used to design microfluidic and optical devices.
