Combination of microfluidic and structure-continual studies in biorheology of blood with magnetic additions

Abstract

Multiscale combination of microfluidic and structure-continual studies is used in order to construct the structure-phenomenological theory of stressed state in arbitrary gradient flows of dilute suspension in blood of rigid axially symmetric elongated particles possessing permanent magnetic moment. The obtained rheological equation is used to examine the revealed viscoelastic behaviour of the considered suspension, explore the possibility of control over its rheological properties with the use of an external magnetic field and investigate the dependence of the suspension effective viscosity on the hematocrit value of blood.
