Resumo

A theoretical model and a method for its approximation analysis were developed to study circulation flows arising in a channel with a non-uniform alternating rotating magnetic field. This channel contains a non-magnetic fluid into which a cloud of ferrofluid is injected, the particles of which are distributed according to the Gaussian law along the channel. It is assumed that the right end of the channel is blocked to simulate a thrombosed vessel. The main goal of the study is to develop a scientific basis for increasing the efficiency of transport of thrombolytic drugs in thrombosed blood vessels using magnetic stimulation.
