Stochastic Locomotive of Nanofluid(s)

This study examines the convection dynamics of superparamagnetic iron oxide nanoparticles (MNPs) in blood fluid. The system under study consists of a liquid with a layer of blood and MNPs with an iron oxide core travelling through a blood artery with cholesterol deposits on the inner lining. It is heated and subjected to an external magnetic field as it passes through the blood vessel. The partial differential equations of momentum and energy conservation were utilized to create the nonlinear three-dimensional governing equations for the system under consideration. Phase portrait, time series, and Hartmann number calculations are used to examine the impact of the magnetic field on the chaotic convection of the MNPs in blood fluid. It has been found that the convection of MNPs stabilizes in a specific direction when magnetized by an external magnetic field. These points to the expanding use of magnetic resonance imaging (MRI) and magnetic drug delivery (MDD) as contrast agents in non-invasive imaging techniques.
