Fluids with suspended microstructure – complex fluids – are common in
micro- and biofluidics and can have fascinating dynamical behaviors. I
will overview modeling and simulation studies of transport and mixing
in complex fluids. These studies will illustrate how microscopic fibers
can become random walkers by dint of their internal degrees of freedom,
how intrinsic oscillations of a driven viscoelastic fluid can mix a
fluid at low Reynolds number, and how hydrodynamically mediated
interactions among many small swimmers can drive, or damp out,
large-scale roiling flows.
