Macroscopic Flows Induced by a Ferromagnetic Fluid under the Action of a Rotating Magnetic Field

We consider the problem of excitation of steady-state circulation flows in a channel filled with a nonmagnetic liquid with an implanted cloud of a ferromagnetic fluid under the action of a uniform rotating magnetic field. Investigations are performed for developing a method for intensification of the drug transport in blood vessels. It is shown that for realistic values of system parameters in a channel of width of a few millimeters, flows with a velocity on the order of several millimeters per second can be developed, which can considerably intensify the transport in thrombose vessels with a stopped blood flow.
