Solute Dispersion in Casson Blood Flow through a Stenosed Artery with the Effect of Magnetic Field

Abstract

Individuals with atherosclerosis cardiovascular disease (aCVD) have a higher risk of cancer than those without aCVD. In chemotherapy, the drug injected into the blood vessels that treat cancer by attacking cells at a specific site in an organ allows better treatment for cancer. One of the most important strategies for directing medication to the site of the cancer is magnetic drug administration such as neodymium magnets treatment. Magnetic drug targeting can reduce the side effects of drugs and optimize magnetic field to speed up treatment. Hence, this study examines the steady solute dispersion in blood flow through a stenosed artery with the effect of magnetic field by using Casson fluid model. The momentum and constitutive equations are solved analytically using integration to obtain the velocity of blood flow. The convective diffusion equation is solved by applying generalized dispersion model (GDM) and integration to obtain steady and unsteady dispersion functions and overall dispersion function. The effects of magnetic field and height of stenosis on the blood flow and solute dispersion are investigated. The results are validated with the previous solution without the effect of magnetic field and height of stenosis. The results showed a good conformity between the two solutions. An increase in magnetic field increase the velocity and steady dispersion function while reducing the unsteady dispersion function and overall dispersion function. However, when the height of stenosis is considered in the problem, it behaves differently for velocity, steady and unsteady dispersion functions and overall dispersion function. It is observed that the solute dispersion in blood flow is affected by magnetic field. The results of the presence study can potentially be used to predict the changes of blood flow behaviour and dispersion process in blood flow. In conclusion, the use of magnetic fields in magnetic therapy aids the body to reduce muscular inflammation and pain. Magnetic field affect the solute dispersion in human blood flow.
