Field-induced self-assembled ferrofluid aggregation in pulsatile flow

Ferrofluid aggregation and dispersion occurs at several length scales in pulsatile flow applications, e.g., in ferrofluidic pumps, valves, and biomedical applications such as magnetic drug targeting. Because of a yet limited understanding, ferrohydrodynamic investigations involving laboratory-scale studies in idealized geometries are of considerable use. We have injected a ferrofluid into a pulsatile host flow and produced field-induced …
